Check and adjust track tension
Warning
● If it’s necessary to operate beneath the
lifted machine or working device,
always use cushion woods, jack, or other
firm and stable supports. Do not access
the area beneath the machine or
working device before it’s firmly
supported. This operation is especially
important for the hydraulic cylinder
operations.
● Guard against high pressure grease.
In the track pensioner, the grease is
injected under high pressure. If the
tension is not adjusted by the following
designated procedure, the grease relief
valve will probably fly out to cause
injuries.
• Never loosen the grease pipe fittings.
• Slowly loosen the grease relief valve. Do
not rotate it for >1 turn.
• Do not place your face, arms, legs, or
body in front of the grease relief valve.
• If no grease flows out when the grease
relief valve is loosened, the valve is
malfunctioned. Please contact a Ken
stone Heavy Machinery service
dealer for repairs.
Checking
1. For rubber tracks, adjust the marking “M”
at the joints to the top center of track
frame.
2. Lift the machine body by working device.
