Move Forward
1. Raise backfill blade, if equipped.
2. Release parking brake, if set, and verify parking brake indicator is off.
3. If using trench cleaner:
• Use ground drive foot control to move forward about 1 foot (30 cm), or until there is enough room
for trench cleaner to enter trench.
• Return ground drive control to neutral to stop forward movement.
• Raise boom slightly, then fully lower trench cleaner to lock it in place.
• Lower boom to desired trench depth.
4. Move ground drive hand control to desired speed. Always start trenching with ground drive gear
selector in position 1 and motor speed switch in low.
5. Increase ground drive speed only as soil conditions permit.
6. Operate engine at full throttle when working.
NOTICE:
• Do not have trench cleaner in working position when starting a trench.
• Do not back up with trench cleaner in working position.
• Do not use trench cleaner in working position in conditions where large rocks can get
between chain and cleaner.
IMPORTANT:
• Ground drive speed/direction can be controlled with foot pedal or hand lever. When
trenching, set ground drive speed with hand lever. Use foot pedal to temporarily adjust
speed if digging conditions change for a short distance.
• For cruise control operation, see page 138.
NOTICE:
• Do not make sharp turns. Lower boom to full depth when turning.
• If an object becomes lodged in chain, move attachment speed/direction control to neutral
and raise boom slightly. Reverse chain direction. If object must be removed manually, turn
engine off and engage parking brake.
