OPERATION

Loading and unloading of any type of machine is dangerous. Never attempt to load or unload the machine without loading ramps or a loading dock. Loading ramps must be strong enough, have a low angle, and correct height. Load and unload the machine on a level surface. Never attempt to load or unload the machine if the ramp incline exceeds 15 degrees. Failure to follow these instructions may result in serious injury or death.

2.Ensure the wheels of the trailer and the tow vehicle have been chocked front and rear.

3.Use the SLOW throttle setting when loading or unloading. Always switch the two-speed control to LOW speed operation when moving in reverse.

4.Drive the machine onto the trailer backwards (en- gine first). This will help prevent instability and keeps the operator “up hill” from the machine during load- ing and unloading.

5.After loading, place chocks at the front and rear of the tracks.

LIFTING

The unloaded TracHorse can be lifted using the single central lift point. Some safety rules may require 3-point lifting. (Center lift point plus 2-points on forward side of rails.)

If lifting with any items in the bed, a 3-point lift is re- quired. (A 3-point lifting sling is available, refer to Acces- sories page.)

TRANSPORTING

1.Read the instructions for loading and unloading in this section.

2.Use chains and binders to secure the load to the trailer.

ROUTINE MAINTENANCE

Good maintenance practices will keep the machine on the job and increase its service life.

A very important maintenance practice is to keep the hy- draulic fluid clean at all times. Contaminated hydraulic fluid causes rapid wear and/or failure of internal parts.

Follow the maintenance instructions contained in the en- gine manual.

ENGINE MAINTENANCE

Follow the maintenance schedule and general mainte- nance instructions in the engine maintenance and op- eration manual furnished with the power unit. Normal maintenance includes:

•Service foam air pre-cleaner every 25 hours of op- eration.

•Service air paper cartridge every 100 hours of op- eration.

•Replace in-line fuel filter every 100-300 hours or sooner if required.

•Replace spark plugs every 100 hours of operation.

•Change engine oil after first 5 hours of operation, then after every 50 hours of operation. If engine has been operating under heavy load or in high ambi- ent temperature, change the oil every 25 hours of operation.

•Change oil filter when engine oil is changed.

•Check oil level daily.

•Remove dirt and debris from engine with a cloth or brush daily. Do not use water spray.

•Clean air cooling system every 100 hours of opera- tion.

HYDRAULIC SYSTEM

MAINTENANCE

Observe the following for maximum performance and service life from the hydraulic system.

•Always keep hydraulic system and fluids clean.

•Keep water out of fluid. (See paragraph below.)

•Keep air out of hydraulic lines. Hydraulic system overheating and foam at the hydraulic tank breather indicate air is present in the lines. Keep all suction line fittings and clamps tight.

•Hydraulic system wear is noted by increased heat during tool operation, reduced tool performance and eventual system breakdown.

•Operate with the fluid temperature at 50–140 °F/ 10–60 °C for improved seal and hose life, and maxi- mum efficiency.
