SAFETY
WHEN USING HAMMER
When using a hammer, pins may fly out or metal particles may be
scattered. This may lead to serious injury. Always do as follows.
If hard metal parts such as pins, bucket teeth, cutting edges, or
bearings are hit with a hammer, there is a hazard that pieces
might be scattered and cause serious personal injury or death.
Always wear safety glasses and gloves.
When hitting pins or bucket teeth, there is a hazard that broken
pieces might be sent flying and injure people in the surrounding
area. Always check that there is no one in the surrounding area.
There is a hazard that the pin hit with strong force may fly out and injure people in the surrounding area.
WELDING WORKS
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 TERMINALS
When repairing or welding the electrical system, wait for approx. one minute after turning off the engine starting
switch key, and then disconnect the negative (-) terminal of the battery to stop the flow of electricity.
SAFETY FIRST 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 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 SPRINGS
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.
