2.) Do not allow anyone to operate your trencher who has not read the Operator’s Manual or has not been instructed on the
safe operation of the trencher.
3.) Never allow children or untrained adults to operate this machine.
4.) Never allow anyone to ride on the trencher while towing.
5.) Never transport cargo on the trencher.
6.) High fluid pressures are developed in hydraulic trenchers. Pressurized fluid escaping though a pin hole opening can
puncture skin and cause severe blood poisoning. Therefore, the following instructions should be followed at all times.
(a) Do not operate the unit with frayed, kinked, cracked or damaged hoses, fittings, or tubing.
(b) Stop the engine and relieve hydraulic system pressure before leaving the trencher unattended or servicing fittings,
hoses, tubing, or other system components.
(c) Do not adjust the pressure settings of the pump or control valve.
(d) Do not check for leaks with your hand. Leaks can be located by passing cardboard or wood over the suspected
area. Look for discoloration. If injured by escaping fluid, see a doctor at once. Serious infection or reaction can
develop if proper medical treatment is not administered immediately.
7.) Keep the operator zone and adjacent area clear for safe trenching. Use extreme caution when operating near structures, utility
lines, or when other workers are present. Call utilities before you dig. Do not straddle trench with trencher. Move trencher
backward and away from the trench as you dig.
8.) If your trencher is intended for use near any unimproved forest, brush, or grass covered land, the engine exhaust should
be equipped with a spark arrestor. Make sure you comply with applicable local, state, and federal codes. Take
appropriate fire-fighting equipment with you.
9.) Trenchers should be only used for trenching. Do not use for other purposes.
10.) Never alter the trencher or any part of its manufactured design.
Preparation
1.) Contact municipalities and utilities to locate buried lines before digging. Do not dig until you have fully investigated the
area. Use extreme caution when overhead or buried utility lines are present.
2.) Be thoroughly familiar with all controls and with the proper use of the equipment.
(a) Always wear safety shoes or heavy boots.
(b) Always wear safety glasses or goggles and approved safety headgear when operating
the machine.

Assembly Instructions
1.) Attach bucket to boom with 1 x 8 pins. Secure 1 x 8 pins with cotter pins.

6
Hydraulic Oil
1.) As you sit in the operator seat, there is an oil sight gauge under left side of the seat. The oil sight gauge is in the
hydraulic oil tank.
2.) Most hydraulic oil is yellow-green in color. If the tank is full, the oil sight gauge should have a yellow-green tint. The
oil level should be up to the black line at the top of the oil sight gauge.
3.) If the oil level is not up to the black line, remove the cap between the seat and control levers. Fill the tank slowly
with 10wt hydraulic oil (Northern Item #4040) while checking the oil sight gauge. Once the tank is full, screw the
cap back on the tank.
Changing the Hydraulic Oil
1.) Remove the drain plug on the bottom part of the frame below the engine. Once the old hydraulic oil is removed,
tighten the drain plug back onto the rank. Be sure to properly dispose of the old hydraulic oil.
2.) Remove breather cap between the seat and control levers. Fill the tank with 10wt hydraulic oil (Northern Item
#4040), while checking the oil level on the sight glass. Pour slowly to allow air to get out of the tank easily. The oil
level should be up to the black line at the top of the oil sight gauge. Screw the cap back onto the tank.
4.) Remove the up-down travel pin and the side-to-side travel pin.
3.) Start the engine and run at slow idle.
5.) Push and pull lever #4 back an forth 6-8 times to remove air from the hydraulic lines. While moving the lever,
watch the clear hose on the right side under the control levers. If there is a steam of bubbles, that is normal. If a
foamy solution is moving through the tube, air is still in the oil. Keep pushing a pulling the lever until the stream of
bubbles appears. After lever #4 is completed, do the same with lever #3, lever #2, and lever #1. Watch the oil
level gauge as you complete each lever. You may have to add more hydraulic oil to the tank to complete all four
levers. Once all four levers are done, fill the tank up to the black line on the oil sight gauge in the hydraulic tank.
The whole hydraulic system contains about 2-1/2 gallons of oil. Shut off the engine.
6.) Reattach the up-down and side-to-side traveling pins.

7
Towing the Trencher
1.) Always obey all state and local regulations when towing the trencher on public roads or highways.
2.) Never allow anyone to sit or ride on your trencher. They could easily fall off and be injured.
3.) The trencher is not a trailer. Do not carry any cargo on the trencher. It can fall off and endanger you and other
drivers.
4.) Be certain the trencher is securely attached to the towing vehicle before towing. The safety chains should be hooked
onto the vehicle with sufficient slack for turning allowance. Always secure trailer hitch with locking bolt.
5.) Be sure to secure the boom up and centered with the up-down and side-to-side travel pins provided. With the
engine off, slightly lower the boom to lock it in place and prevent it from swinging. Also, curl the bucket and arm in to
achieve a compact towing configuration.
5.) Be sure the outriggers are secured in the vertical position before towing. Do not tow with outriggers down.
6.) Be aware of the added length of the trencher when you are towing it behind a vehicle. Be careful not to jack-knife
your trencher when backing the vehicle.
7.) Towing speed should be according to driving conditions. Use a “Slow Moving Vehicle” sign when driving on roads.
Take extra care when driving on rough terrain.
8.) Disconnect the trencher from the towing vehicle before using the trencher.
9.) Grease wheel bearings annually, or after long trips, to extend the life of your bearings.
