SAFETY
SAFETY FIRST WHEN USING HIGH-PRESSURE GREASE TO ADJUST TRACK
q 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.
q When loosening grease drain plug (1) to loosen the track
tension, never loosen it more than one turn. Loosen the
grease drain plug slowly.
q 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.
