• The trencher is a small, operator propelled, chain-type trencher designed for the installation of lines that require a narrow shallow trench. It has more than enough power to trench through the toughest soils, however, because of its small size, low horse power and trench capacity, it is limited in what it is capable of doing. The job site, soil  conditions, job used to do the job.
• The digging chain has a tendency to pull the trencher in the opposite direction you want to dig. For this reason, be sure that the digging teeth are not in contact with the  ground or other objects while starting the engine and that the wheel lock device engages before lowering the digging bar into the ground. Be sure that you have a firm  grip on the machine and are ready to control it when the digging bar comes in contact with the ground.
• The trencher has a tendency to “hop” or “buck” under certain conditions. This can be the result of certain soil conditions or buried objects that the trencher cannot cut  through or lift to the surface. The trencher must be stopped and the object removed, or restarts the trench beyond the object.

Operating the Trencher

Operating the Trencher
It may be helpful to better familiarize yourself with the features of your Trencher before beginning the steps outlined in this chapter.

CAUTION:
A. Read and understand all instructions, safety precautions, and/or warningslisted in “PART I: General Safety Rules” before operating the TRENCHER. If any doubt or  question arises about the correct or safe method of performing anything found in this manual, please contact the dealers inyour area.
B. Before loading and operating the Trencher, always wear protective gear, including safety goggles, hearing protection, tight-fitting gloves without draw String or loose cuff and steel toed shoes.

Starting
Be sure the depth control is in the “0” depth position and move both stop switches to the “ON” position. Always stand to the rear of the trencher, away from the side  delivery auger and digging chain while starting the engine. Always start the trencher at the job site and allow it to warm up. While the machine is running, check that all  controls are working properly before using.

Start the engine following the procedures:

• Move the choke control lever to the “CHOKE” position (should only be needed if the engine is cold).
• Move the throttle control lever to the “FAST” position.
• Recoil Start: Turn the Ignition Switch to the “On” position. Push the handle of flameout switch and grasp the recoil starter handle and slowly pull until you feel resistance. Let the cord retract a little bit then pull the cord rapidly to start the engine. One or two pulls usually starts the engine.
• Electric Start: Turn and hold the Key in the start position until Engine starts then let the key return to run position.
• Move the choke control lever (if used for cold engine) slowly back to the “RUN” position when the engine is running well.
• If the Trencher has not been running (cold engine), warm up the engine by running the engine at half throttle for 3 to 4 minutes, then advance the engine throttle control to the maximum speed.

Trenching
Be sure the digging chain is not turning when the engine is at an idle. Be sure the engine is off or at idle before moving the trencher the job site.
NOTE: All depths are approximate. Actual depth may vary depending upon soil conditions and trencher blade wear.
Also, soil conditions and operator experience will dictate actual trenching action and speed
A general description on how to trench:
Anticlockwise rotate the depth control handle and lift the chains, lock the antiforward control handle, then the trencher can be push forward

• Push forward the trencher to the work site, loose the anti-forward control handle, then the trencher can only move backwards. Clockwise rotate the depth control handle  and descend the chains to your desired depth.

Notes:

• Lock: When we put the anti-forward control handle in the slot, the anti-forward controller lift up, don’t touch the wheel gear, we can push forward.
• Loose: When we pull back the ant-forward control handle, it will automatically loose the anti-forward controller down on the wheel gear, the trencher can’t move forward and can only move backwards
  

Stopping
There are two stop switches on the trencher; one on the handle bar and one on the engine. Refer to the engine manual for the switch location on your trencher. The operator can turn the trencher off at any time by switching either stop switch to the “OFF” position. Both switches must be “ON” before the engine can start.

Maintaining Your Trencher
