Operation Instructions
1.) Before starting this trencher, review the “Rules for Safe Operation.” Failure to follow these rules may result in
serious injury to the operator or bystanders. The machine owner should instruct all operators in safe trencher
operation. Call all utilities or a one-call service to mark utility lines.
2.) Before digging with the trencher, make sure trencher is in digging mode.
3.) Run your engine only in well ventilated areas. Carbon monoxide fumes are odorless and colorless. Inhaling
these gases can cause carbon monoxide poisoning. Never leave the machine unattended with the engine
running.
4.) Never operate the machine when under the influence of alcohol, drugs, or medication.
5.) Always operate the trencher with all safety equipment in place and all controls properly adjusted for safe
operation.
6.) Always operate the trencher at the manufacturers recommended speed. Always be ready to stop the engine
and disengage the boom in case of emergency.
7.) Always keep hands, feet, and all other body parts clear of moving parts.
8.) Do not straddle or climb over the boom. Serious injury can result from a slip while straddling or climbing.
9.) Be sure the terrain allows wheels and outriggers to make firm contact with ground.
10.) Before digging, take the time to learn the control valves and the function each performs. Learn how they work in
conjunction with each other. A description of what each control valve does is illustrated on the valve mounting plate.
Practice using the control valves before digging, it will make for safer and more efficient trenching.
11.) Position bucket with teeth perpendicular to the ground.
12.) Extend the arm out. Then, lower the boom until resistance is met. Do not make the outriggers leave the ground.
13.) Curl the arm or bucket to scoop earth. Should either of these movements make the outriggers move, raise the boom
slightly to make the outriggers dig in to provide support.
14.) Once the digging motion is complete, completely curl the bucket. Raise rotate the boom to clear the trench.
15.) Empty the bucket. Repeat steps 11-15 for each scoop.
16.) Do not attempt to straddle the trencher over a trench. It could fall into the excavation site and cause serious injury.
Move trencher backward and away from trench as you dig.
17.) Do not refuel the engine until it has cooled for several minutes.
Moving the trencher
WARNING! It is possible to move the trencher under its own power when it is digging mode. This movement should be
done with caution. Do not attempt these maneuvers until fully comfortable with the controls and only when the trencher is
away from hazards. Do not attempt to straddle the trencher over a trench. It could fall into the excavation site and cause
serious injury. Move trencher backward and away from trench as you dig.
Move Backward
1.) Make sure trencher is in digging mode.
2.) Curl the arm in and lower the boom to rest bucket teeth into the ground. The bucket should rest in the center of the
work area, two feet from the front of the trencher frame.
3.) Raise the unit off its outriggers by lowering the boom.
4.) Once the outriggers are clear of the ground, rotate the arm out. This will cause the trencher to move backward.
5.) Raise the boom until weight is on the outriggers again.
Move Forward
1.) Make sure trencher is in digging mode.
2.) Rotate the arm out and lower the boom to rest bucket teeth into the ground. The bucket should rest in the center of
the work area.
3.) Raise the unit off its outriggers by lowering the boom.
4.) Once the outriggers are clear of the ground, curl the arm in. This will cause the trencher to move forward.
5.) Raise the boom until weight is on the outriggers again.
Move Side to Side
1.) Make sure trencher is in digging mode.
2.) Raise boom and swing boom to the side where the new work area is located.
3.) Lower boom to rest bucket teeth into the ground and raise outriggers off the ground.
4.) Swing boom in the direction opposite the desired movement of the machine.
5.) Once the unit is facing the new work area, raise the boom until weight is on the outriggers again.
