OPERATION

CHECK BEFORE STARTING ENGINE, ADJUST

WALK-AROUND CHECK
1. Check for wear of the point at the tip of the shank, check the mounting condition, and check for damage to the
rivets. If any abnormality is found, replace or repair.
PRECAUTIONS WHEN OPERATING
q Travel in low speed and lower the ripper gradually when starting to move the machine off. When the optimum
digging depth is reached, move the control lever to the HOLD position.
Do not dig the shank in deep when starting digging operations.
q During ripping operations, never turn the machine suddenly or travel in reverse. When turning the machine
suddenly or traveling in reverse, raise the shank from the ground surface.
q When carrying out digging operations with only one shank, always use the center shank. Remove both side
shanks.
q When starting to travel up a steep slope or when reaching the bottom of the slope, the point may touch the
ground. On hard ground, there is danger of the point breaking if it touches the ground, so raise the shank to
the maximum height.
