SAFETY MAINTENANCE INFORMATION
REMOVING BATTERY TERMINALS
When repairing the electrical system or when carrying out electrical welding, remove the negative (-) terminal of the
battery to prevent the flow of current.
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.
SAFETY RULES FOR HIGH-PRESSURE OIL
The hydraulic system is always under internal pressure. When inspecting or replacing piping or hoses, always
check that the pressure in the hydraulic circuit has been released. If the circuit is still under pressure, it will lead to
serious injury, so always do as follows.
Always release the pressure before starting any inspection or replacement operation.
If there is any leakage from the piping or hoses, the surrounding area will be wet, so check for cracks in the piping
and hoses and for swelling in the hoses.
When carry out inspection, wear safety glasses and leather gloves.
There is a hazard that high-pressure oil leaking from small holes
may penetrate your skin or cause blindness if it contacts your
eyes directly. If you are hit by a jet of high-pressure oil and suffer
injury to your skin or eyes, wash the place with clean water, and
consult a doctor immediately for medical attention.
