DANGER

WARNING

CAUTION

Mandatory Safety Shutdown Procedure

Before cleaning, adjusting, lubricating, servicing the unit or leaving itunattended:

1. Move the drive control handle(s) to the “neutral” position.

2. Lower the lift arm and attachment completely. If the lift arm must be leftin the “raised” position, BE SURE to properly engage the lift arm supportdevice (page 13).

3. Move the throttle to the low idle position, shut off the engine andremove the key.

4. Before exiting, move the lift/tilt control(s) to verify that the controls donot cause movement of the lift arm and hitch.

Safety Reminders

Before Starting

�Do not modify the ROPS/FOPS unless instructed to do so in installationinstructions. Modifications such as welding, drilling or cutting canweaken the structure and reduce the protection it provides. A damagedROPS/FOPS cannot be repaired — it must be replaced.

�To ensure safe operation, replace damaged or worn-out parts withgenuine Mustang service parts.

�Mustang skid steer loaders are designed and intended to be used only withMustang attachments or approved referral attachments. Mustang cannotbe responsible for operator safety if the loader is used with anon-approved attachment.

�Remove all trash and debris from the machine each day, especially in theengine compartment, to minimize the risk of fire.

�Always face the loader and use the hand holds and steps when getting onand off the loader. Do not jump off the loader.

�Never use starting fluid (ether).

�Walk around the machine and warn all nearby personnel before startingthe machine.

�Always perform a daily inspection of the machine before using it. Lookfor damage, loose or missing parts, leaks, etc.

During Operation

�The terrain, engine speed, load being carried and abrupt controlmovements can affect machine stability. IF MISUSED, ANY OF THE ABOVE

FACTORS CAN CAUSE THE LOADER TO TIP, THROWING YOU FORWARD OR

OUT OF THE UNIT, CAUSING DEATH OR SERIOUS INJURY. Therefore,always have the operator restraint bar lowered and wear the seatbelt.Operate the controls smoothly and gradually at an appropriate enginespeed that matches the operating conditions.

5 908271/AP0301

�Always travel with the heavier end of the loader toward the top of theincline for additional stability when operating on inclines or ramps.

�Do not raise or drop a loaded bucket or fork suddenly. Abrupt movementsunder load can cause serious instability.

�Never push the lift control into the “float” position with the bucket orattachment loaded or raised, because this will cause the lift arm to lowerrapidly.

�Do not drive too close to an excavation or ditch; be sure that thesurrounding ground has adequate strength to support the weight of theloader and the load.

�Never carry riders. Do not allow others to ride on the machine orattachments, because they could fall or cause an accident.

�Always look to the rear before backing up the skid steer loader.

�Operate the controls only from the operator’s seat.

�Do not exceed the rated operating load of the machine.

�Always keep hands and feet inside the operator’s compartment whileoperating the machine.

�New operators must operate the loader in an open area away frombystanders. Practice with the controls until the loader can be operatedsafely and efficiently.

�Exhaust fumes can kill. Do not operate this machine in an enclosed areaunless there is adequate ventilation.

�When you park the machine and before you leave the seat, check therestraint bar for proper operation. The restraint bar, when raised, appliesthe parking brake and deactivates the lift/tilt controls.

Maintenance

�Never attempt to by-pass the keyswitch to start the engine. Use only thejump starting procedure detailed in the Service chapter of this manual.

�Never use your hands to search for hydraulic fluid leaks. Instead, use apiece of paper or cardboard. Escaping fluid under pressure can beinvisible and can penetrate the skin and cause serious injury. If any fluid isinjected into your skin, see a doctor at once. Injected fluid must besurgically removed by a doctor or gangrene may result.

�Always wear safety glasses with side shields when striking metal againstmetal. In addition, it is recommended that a softer (chip resistant) materialbe used to cushion the blow. Failure to heed could lead to serious injury tothe eyes or other parts of the body.

�Do not smoke or have any spark producing equipment in the area whilefilling the fuel tank or while working on the fuel or hydraulic systems.

WARNING

WARNING

WARNING

Note: With the keyswitch OFF and thesolenoid valve working, the lift arm willstay raised when the lift control is moved tolower the lift arm. If the valve does not holdthe lift arm and it begins to lower, do notleave the operator’s compartment. Instead,have someone store the support device foryou. Then, contact your Mustang dealerimmediately to determine why the lift armlowers while the keyswitch is OFF.

4. To store the support device, raise it upuntil it contacts the lift arm. Slide the lock pin through the supportdevice and catch under the lift arm. Once the pin is secure, flip the lockpin loop so that it locks the pin in.

Safety Interlock System

NEVER defeat the safety interlock system bymechanically or electrically bypassing any switches, relays orsolenoid valves.

An interlock system is used on the loader for operator safety. Together withsolenoid valves, switches and relays, the interlock system:

» Prevents the engine from starting unless the operator is sitting on the seatand the operator restraint bar is down.

» Disables the lift arm, attachment tilt and wheel drives anytime theoperator leaves the seat, turns the keyswitch to OFF or raises the restraintbar.

» Disables the engagement of the auxiliary hydraulics anytime the restraintbar is raised or the keyswitch is OFF.

Testing the Safety Interlock System

Before leaving a parked machine, check the safety interlock system forproper operation:

Restraint Bar

With the engine running, raise the restraint bar. Test each of thecontrols. There should be not more than a slight movement of the liftarm, hitch and machine. If there is any significant movement,troubleshoot and correct the problem immediately. Contact your dealerif necessary.

Dual T-Bar Controls

Your Mustang loader may be equippedwith the dual T-Bar control option. The leftT-Bar controls the drive and the right T-Barcontrols the lift/tilt.

Drive Control

Forward, reverse, speed and turningmaneuvers are accomplished by movementof the left T-Bar. To go forward, push thecontrol forward; for reverse, pull thecontrol rearward. To turn right, turn the control clockwise; to turn left, turnthe control counterclockwise. For gradual turns, move the T-Bar slightlyforward or rearward. For sharp turns, do not move the control forward orrearward.

Moving the T-Bar farther from neutral increases the speed steadily to themaximum travel speed. Tractive effort decreases as speed increases. To getmaximum tractive effort, move the T-Bar only part way from the neutralposition. The engine will stall if the control is moved too far forward whenloading the bucket.

Be sure the T-Bar controls are in neutral beforestarting the engine. Operate the T-Bars gradually and smoothly.Excessive speed and quick T-Bar movements without regard forconditions and circumstances are hazardous and could causean accident.

Lift/Tilt Control

Moving the lift arm and tilting the attachment are accomplished bymovement of the right T-Bar. To raise the lift arm, pull the control straightrearward; to lower the lift arm, push the control straight forward. To tilt theattachment downward, twist the control clockwise; to tilt the attachmentup or back, twist the control counterclockwise.

Note: The speed of the lift/tilt motion is directly proportional to the amountof T-Bar movement and engine RPM.

To place the lift arm in the detent (float) position, push the right T-Bar all theway forward, into the detent. This position allows the lowered lift arm tofloat while traveling over changing ground conditions.

Never push the lift/tilt T-Bar control into thefloat position with the attachment loaded or raised, because thiswill cause the lift arm to lower rapidly.

WARNING

WARNING

Hand/Foot Controls

Your Mustang loader may be equipped withthe hand/foot control option. The handlescontrol the drive and the foot pedals controlthe lift/tilt.

Drive Controls

Forward, reverse, speed and turningmaneuvers are accomplished by movementof the control handles. To go forward, pushboth handles forward; for reverse, pullboth handles rearward. For turning, moveone handle farther forward or rearward thanthe other handle. Turn direction is determined by which handle is moved thefarthest forward; to turn left, move the right handle farther forward than theleft handle. For sharp turns, move the handles in opposite directions.

Moving the handles farther from neutral increases the speed steadily to themaximum travel speed. Tractive effort decreases as speed increases. To getmaximum tractive effort, move the handles only part way from the neutralposition. The engine will stall if the controls are moved too far when loadingthe bucket.

Be sure the controls are in neutral beforestarting the engine. Operate the controls gradually andsmoothly. Excessive speed and quick control movementswithout regard for conditions and circumstances are hazardousand could cause an accident.

Lift/Tilt Controls

Moving the lift arm and tilting the attachment are accomplished bymovement of the foot pedals. The left pedal raises and lowers the lift arm;the right pedal tilts the attachment. To raise the lift arm, use your heel topush down on the left pedal; to lower the lift arm, use your toes to push downon the left pedal. To tilt the attachment downward, use your toes to pushdown on the right pedal; to tilt the attachment up or back, use your heel topush down on the right pedal.

Note: The speed of the lift/tilt motion is directly proportional to the amountof pedal movement and engine RPM.

To place the lift arm in the detent (float) position, use your toes to push theleft pedal all the way down, into the detent. This position allows the loweredlift arm to float while traveling over changing ground conditions.

Never push the left pedal into the float positionwith the attachment loaded or raised, because this will cause thelift arm to lower rapidly.

Do not use starting fluid (ether) with preheatsystems. An explosion can result which can cause enginedamage, injury or death.

Push the PREHEAT button on the instrument panel for a maximum of 30seconds to preheat the engine. If the temperature is below 32° F (0° C), trythe following to make starting the engine easier:

» Replace the engine oil with SAE 5W30.

» Make sure the battery is fully charged.

» Install a block heater on the engine.

Let the engine run for a minimum of five minutes to warm the engine andhydraulic fluid before operating the loader.

Stopping the Loader

The following procedure is the recommended sequence for stopping theloader:

1. Check that the drive control handle(s) is(are) are in “neutral” position.

2. Lower the lift arm and rest the attachment on the ground.

3. Pull the throttle lever back to the idle position (and/or take your foot offthe accelerator pedal for hands-only controlled machines).

4. Turn the keyswitch to the OFF position to shut off the engine.

5. Raise the restraint bar, unlatch the seatbelt and grasp the hand holdswhile climbing out of the operator’s compartment.

Note: The skid loader is equipped with a spring- applied automatic parkingbrake. The parking brake is engaged when the operator lifts the restraintbar, leaves the operator’s seat, shuts off the engine or when the brake switchis applied (the bottom half of the switch is pushed in).

Parking the Loader

Park the loader on level ground away from traffic. If this is not possible, parkthe loader across the incline and block the tires to prevent movement.

WARNING

Jump Starting the Battery

If the battery becomes discharged or does not have enough power to start theengine, use jumper cables and the following procedure to jump start theengine.

The only safe method for jump starting adischarged battery is for two people to perform the followingprocedure. The second person removes the jumper cables sothat the operator does not have to leave the operator’scompartment with the engine running. Never make jumper cableconnections directly to the starter solenoid of either engine. Donot start the engine from any position other than the operator’sseat and then only after being sure all controls are in “neutral.”

Closely follow the procedure in order to avoid personal injury. Inaddition, wear safety glasses to protect your eyes. Avoid leaningover the batteries while jump starting.

Do not jump start the battery if it is frozen, because it may ruptureor explode. Warm the battery to 60 F (16 C) before connecting toa charger.

Note: Be sure the jumper battery is a 12 volt D.C. battery.

1. Turn the keyswitches of both machines to OFF. Be sure the machines arein “neutral” and NOT touching each other.

2. Connect the positive (+) jumper cable to the positive (+) batteryterminal on the disabled loader first. Do not allow the jumper’s positivecable clamps to touch any metal other than the positive (+) batteryterminals. Connect the other end of the positive jumper cable to thejumper machine’s battery positive (+) terminal.

3. Connect the negative (-) jumper cable to the jumper machine’s batterynegative (-) terminal.

Important: Do not use the loader frame as ground or damage will occur tothe engine-to-frame groundwire.

4. Make the final negative (-) jumper cable connection to the disabledloader’s engine block (ground) — NOT to the disabled battery’snegative (-) post. When connected to the engine, keep the jumper clampaway from the battery, fuel lines and moving parts.

5. Be sure the brake switch is engaged and that the controls are in neutral.Start the engine. If it does not start at once, start the jumper machine’sengine to avoid excessive drain on the booster battery.

6. After the disabled loader is started and running smoothly, have thesecond person remove the jumper cables (negative (-) jumper cablefirst) from the jumper machine’s battery and then from the disabledloader while being sure NOT to short the two cables together.

Allow sufficient time for the skid loader alternator to build up a charge in thebattery before attempting to operate the loader or shut off the engine.

Mounting Tires

Inflating or servicing tires can be dangerous.When possible, trained personnel should service and mounttires. To avoid possible death or serious injury, follow the safetyprecautions below:

1. Be sure the rim is clean and free of rust.

2. Lubricate the tire beads and rim flanges with a soap solution. Do not useoil or grease.

3. Use a clip-on tire chuck with remote hose and gauge, allowing you tostand clear while inflating the tire. Do not place your fingers on the tirebead or rim during inflation.

4. Never inflate beyond 35 PSI (240 kPa) to seat the beads. If the beadshave not seated by the time the pressure reaches 35 PSI, deflate theassembly, reposition the tire on the rim, lubricate both parts andre-inflate. Inflation pressure beyond 35 PSI with unseated beads maybreak the bead or rim with explosive force sufficient to cause death orserious injury.

5. After seating the beads, adjust the inflation pressure to therecommended operating pressure.

6. Do not weld, braze or otherwise attempt to repair and use a damagedrim.

Check Tire Pressure

WARNING

Electrical System

Circuit Breakers

The circuit breakers for the loader are located on the right instrument panel.There is also a 35 amp main circuit breaker located on the right side of theengine compartment, directly behind the ROPS.

Battery

Before servicing the battery or electricalsystem, be sure the battery disconnect switch (if equipped) is inthe “OFF” position. If not equipped with a disconnect switch,disconnect the ground (-) terminal from battery.

The battery on the loader is a 12 volt, wet-cell battery. To access the battery,open the rear door and lift the engine cover.

The battery top must be kept clean. Clean it with an alkaline solution(ammonia or baking soda and water). After foaming has stopped, flush thebattery top with clean water. If the terminals and cable connection clampsare corroded or have a build-up, disconnect the cables and clean theterminals and clamps with the same alkaline solution.

Explosive gas is produced while a battery is inuse or being charged. Keep flames or sparks away from thebattery area. ALWAYS charge the battery in a well-ventilatedarea.

Never lay a metal object on top of a battery, because a shortcircuit can result.

Battery acid is harmful on contact with skin or fabrics. If acidspills, follow these first-aid tips:

1. Immediately remove any clothing on which acid spills.

2. If acid contacts the skin, rinse the affected area with runningwater for 10 to 15 minutes.

3. If acid contacts the eyes, flood the eyes with running water for10 to 15 minutes. See a doctor at once. Never use any medicationor eye drops unless prescribed by the doctor.

4. To neutralize acid spilled on the floor, use one of the followingmixtures:

a. 1 pound (0,5 kilogram) of baking soda in 1 gallon (4 liters)of water

b. 1 pint (0,5 liters) of household ammonia in 1 gallon (4liters) of water

Whenever the battery is removed, be sure to disconnect thenegative (-) battery terminal connection first.

Note: The densities listed are average values and intended only as a guidefor bucket selection. For a material that is not in the table, obtain its densityvalue before selecting the appropriate bucket.

59 908271/AP0301

To use the table, find the material name and see what its maximum densityis. Then, multiply the loader rating of the attachment by the material densityto determine if the attachment can safely be used. See page 58 for a listing ofattachments and their loader ratings.

Note: Where the material density is listed as a range (clay at 80-100 lb/ft3,for example), always use the maximum density (100 lb/ft3 in this example)for making calculations. Also, see the following examples.

Example 1: If clay (density of 80-100 lb/ft3) is to be hauled using a 2032model loader using Dirt/Construction Bucket #808248, the bucket capacityis 9.5 ft3 and the loader rating is 1250 lb. Multiply the density of clay (100lb/ft3) by the capacity of the bucket (9.5 ft3) to achieve the weight beingcarried. (100 lb/ft3 x 9.5 ft3 = 950 lb) This number is less than the machinerating so you could safely use this bucket in this application.

Example 2: If potash (density of 68 lb/ft3) is to be hauled using a 2022model loader using Utility Bucket #808249, the bucket capacity is 13.5 ft3

and the loader rating is 850 lbs. Multiply the density of potash (68 lb/ft3) bythe capacity of the bucket (13.5 ft3) to achieve the weight being carried (68lb/ft3 x 13.5 ft3 = 918 lb). This number exceeds the machine rating and acounterweight will be required. With the counterweight installed, the loaderrating increases to 950 lb (850 lb loader rating + 100 lb counterweight). Thebucket can now be used safely in this application.
