WARNING!
Do not move choke control to CLOSE to stop engine. Backfire or engine damage may occur.
6 Maintenance
A proper maintenance and lubrication will help the machine in a perfect working condition.
Preventive maintenance
1. Turn off engine and disengage all command levers. Engine must be cool.
2. Inspect the general condition of the unit. Check for loose screws, misalignment or binding of moving parts, cracked or
broken parts, and any other condition that may affect its safe operation.
3. Remove all debris and other materials that may have accumulated to the track and unit. Clean after each use. Then use a
premium quality lightweight machine oil to lubricate all moving parts.
WARNING!
Never use a “pressure washer” to clean your unit. Water can penetrate tight areas of the machine
and its transmission case and cause damage to spindles, gears, bearings, or the engine. The use
of pressure washers will result in shortened life and reduce serviceability.
Adjusting clutch
As clutch wears out, the same lever could have a wider opening, being so uneasy to use. This means that it is necessary to
adjust the cable, setting clutch lever on its original position acting on the adjustment device and on counter-nut.
Adjusting steering
If you have difficulty steering the unit, you will need to adjust the steering levers with the special adjusters. Slacken off the
locknut and unscrew the adjusters to eliminate the play in the cable, which can occur after initial use or normal wear. Be very
careful not to unscrew the adjusters too much because this can create another problem: the loss of traction. Remember to tighten
the locknut when you have finished.
Lubrication
The gearbox is pre-lubricated and sealed at the factory.
• Check oil level every 50 hours of working. Remove the plug and check, with machine horizontal, oil reaches the two
notches. If necessary, add the oil.
• Use portable tool lithium #0 grease such as Lubriplate 6300AA , Lubriplate GR-132, or Multifak, e.g. EP-O.
•
Oil must be replaced when hot by unscrewing filler cap and plug equipped with an oil dipstick. When oil is completely
drained, replace filler cap and fill up with new oil.
Tire pressure
Check the pressure of tires periodically to make sure they are properly inflated. Recommended pressure is 30 psi/2 bar for all
the tires.
WARNING!
Separation of tire and rim parts is possible when they are serviced incorrectly.
1. Do not attempt to mount a tire without the proper equipment and experience to perform the job.
2.
Do not inflate the tires above the recommended pressure.
3. Do not weld or heat a wheel and tire assembly. Welding can structurally weaken or deform the wheel. Heating can
cause an increase in the air pressure resulting in burst.
4.
Do not stand in front or over the tire assembly when inflating.
Engine maintenance
Refer to the Engine Manual included in your unit for the information on engine maintenance. Your engine manual provides
detailed information and a maintenance schedule for performing the tasks.
