SAFETY
PRECAUTIONS FOR MAINTENANCE
REPAIR WELDING
Welding operations must always be carried out by a qualified welder and in a place equipped with proper equipment.
There is a hazard of gas, fire, or electrocution when carrying out welding, so never allow any unqualified personnel
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 system
under high pressure. If the specified procedure for maintenance
is not followed when making adjustment, grease drain valve (1)
may fly out and cause serious injury or damage.
When loosening grease drain valve (1) to loosen track tension,
never loosen it more than one turn. In doing so, loosen the valve
slowly.
Never put your face, hands, feet, or any other part of your body
directly in front of grease drain valve (1).
DO NOT DISASSEMBLE RECOIL SPRING
Never attempt to disassemble the recoils spring assembly. It contains a spring under high pressure which serves
as a shock absorber for the idler. If it is disassembled by mistake, the spring will fly out and cause serious injury.
When it becomes necessary to disassemble it, ask your Komatsu distributor to do the work.
