[2] Reducing tension
WARNING
• Do not loosen the plug (1) by more than one
turn. Loosening by more than one turn risks
the plug (1) flying out because the grease
inside is at high pressure.
Do not loosen any parts except the plug (1).
Also do not position your face in the
direction where the plug (1) is mounted.
• Discharging grease using procedures other
than described below is extremely
dangerous. If the crawler tracks are not
loosened, contact us or our sales service
agency for repairs.
1.
Remove the bolt (2) below the plug (1).
2.
Remove the guard (3).
3.
Slowly loosen the plug (1) to discharge the
grease.
When loosening the plug (1), loosen it by only
one turn at the most.
If the grease cannot be smoothly
discharged, move the machine back and
forth slightly.
4.
Screw in plug (1).
5.
To ensure that the correct tension is applied,
keep the engine at low idle to move forward a
distance equal to the length of the crawler
tracks in contact with the ground, and then
slowly stop.
6.
Check the tension of the crawler tracks again.
If the tension is not correct, readjust.
WINDOW WASHER
SOLUTION
INSPECTION/REFILLING
If air is trapped in the window washer solution,
check the level of solution in the window washer
tank (1). If it is too low, replenish with car window
washer solution.
When replenishing the window washer
solution, take care to keep it free from
dust.
The user can select one of two types provided for
different temperatures of -10 °C (for general use)
and for -30 °C (for extremely cold regions) by also
taking into account the area and season.
