CONTROLS

1. KEYED IGNITION SWITCH: This remote switch is located with the other trencher controls for
your convenience. Use it to start and stop the engine equipped with an electric starter. Refer to the
ENGINE START UP PROCEDURE.
2. ENGINE: This is the throttle - controls engine speed. Operate at full throttle (all the way forward).
3. CLUTCH LEVER: Located on left handlebar. Squeeze to activate the track drive and dig chain.
All motion stops when the lever is released. DIGGING CHAIN control must be held in "ON"
position as clutch lever is raised in order to activate Dig Chain.
4. T-HANDLE CONTROL Controls the travel direction and speed after clutch lever is raised.
• Pushing the T-handle forward from the neutral position causes the machine to move forward.
• Pulling the T-handle back from neutral position causes the machine to move backward.
• Moving the T-handle farther from the neutral position increases the speed.
• Steer the trencher by twisting the T-handle to the left or right. This causes the track on one side to
rotate at a different speed or direction than the opposite track.
• Very slow speed is required for trenching in most conditions.
NOTE: Be sure operator understands that the machine moves BACK when trenching, not forward.
5. DIG CHAIN ON/OFF CONTROL: To trench, hold lever in ON position while clutch lever is
raised. The ON/OFF lever will stay in position as long as the clutch lever is held. This automatically
will activate the CHAIN FORWARD/REVERSE LEVER to FORWARD position.
6. CHAIN FORWARD/NEUTRAL/REVERSE LEVER: Use this lever to reverse chain to help clear
debris from the chain. The DIG CHAIN ON / OFF lever must be in "OFF" position to put the
CHAIN F/N/R lever in reverse.
7. DIGGING BOOM CONTROL: Pull to raise the digging boom and push to lower the boom.
During normal operation you will hear the relief valve working.
8. PARKING BRAKE: It is located behind the left hand track motor. Move the handle down to
engage the brake, and up to disengage it.
