Daily checks

any dirt from hydraulic cylinders
and grapple arms.

foreign objects from the tool.

accumulators are intact.
Check
that the quick coupler, chassis
and bolted joints are intact.

Greasing instructions
The grapple is fitted with sliding bearings
which have greasing intervals of up to
50 hours, depending on the environment.
When operating in dirty, dusty and
damp environments, we recommend
reducing greasing intervals to no more
than 16 hours to improve sliding bearing
durability.
Expander pins
Expander pins are secured in their
bearing position through the expansion,
when tightened, of tapered sleeves at
the ends of the pins that form a shrink
fit. Check and retighten the grapple
expander pins for the first time after
10 operating hours, and then every
250 operating hours. Grease the tapered
expanders and pins on reinstallation.
The MG20 grapple is fitted with a bearing
that is secured with a locking nut.
Tightening torque when checking and
re-tightening is 17 Nm.
