Check steel pad screw torques.............................Every 250 hours (after the first 50 hours during the run-in period)
Check the rubber track pads (optional)........................................................................... Every 10 hours or every day
IMPORTANT: If the tracks are too tight, they wear
quickly. If tracks are not tight enough, they wear
quickly and the links can catch on the sprocket wheel
or slide off the idler wheel or the sprocket wheel.
Clean the tracks after work.
IMPORTANT: For rubber tracks (Optional), avoid
pivoting on the spot as this could cause the tracks to
wear out quickly and could also cause jamming of
stones, rocks, etc. Avoid working in an area full of
rock rubble or debris, pieces of reinforced concrete or
striated plates.
CLEANING
When the machine has been working in mud, a
reduction in temperature can cause the mud to
solidify.
1. Place the upperstructure at right angles to the
undercarriage. Use the attachment to press on
the ground and lower the boom until the track is
raised off the ground.

track forwards and then in reverse, to remove the
mud.
4. Repeat Steps 1 to 4 for the other track.
NOTE: For machines fitted with the dozer blade, the
machine can be lifted by completely lowering the
blade and by using the attachment as a support on
the ground, opposite the blade.
