SAFETY PRECAUTIONS FOR MAINTENENCE
2-31
REPAIR WELDING
Welding operations must always be carried out by a qualified welder and in a place equipped with a proper equip-
ment. There is a hazard of fire or electrocution when carrying out welding, so never allow any unqualified person-
nel to carry out welding.
REMOVING BATTERY TERMINAL
When repairing the electrical system or when carrying out electrical welding, remove the negative (-) terminal of
the battery to prevent the flow of current.
PRECAUTIONS WHEN USING HIGH-PRESSURE GREASE TO ADJUST
TRACK TENSION
● Grease is pumped into the track tension adjustment sys-
tem under high pressure.
If the specified procedure for maintenance is not followed
when making adjustment, grease drain plug (1) may fly out
and cause serious injury or property damage.
● When loosening grease drain plug (1) to loosen the track
tension, never loosen it more than one turn. Loosen the
grease drain plug slowly.
● Never put your face, hands, feet, or any other part of your
body close to grease drain plug (1).
DO NOT DISASSEMBLE RECOIL SPRING
The recoil spring assembly is used to reduce the impact on the idler. It contains a spring under high pressure, so if
it is disassembled by mistake, the spring will fly out and cause serious injury or even death. Never disassemble the
recoil spring.
