GENERAL INFORMATION
Your trencher was designed to be as simple and as trouble free as possible.
The purpose of this section is to help you in the event that a problem does develop.
Why we cannot possibly cover every problem that might occur, you will find that
those that are most common are covered here.
PROBLEM: Digging chain will not turn
POSSIBLE CAUSE AND REMEDY:
1. Quick coupler not completely engaged. Check to see that all couplers are
matched pairs and engaged correctly. Check coupler hook-up information
(See Section E) for proper hydraulic hose routing.
2. Quick coupler failure. Check couplers for dirt, rust, or other contaminates
that could effect coupler engagement. Clean or replace couplers as needed.
3. Obstruction in hydraulic hose. Remove hydraulic hoses and couplers one at
a time and check flow through hose by blowing through the hose or by pour-
ing hydraulic fluid through the hose. Clean or replace hose as needed.
4. Skid steer relief valve stuck open. Have relief valve serviced and checked by
an authorized dealer.
5. Skid steer auxiliary valve not operating properly. See skid steer operator's
manual or dealer for information and help.
6. Hydraulic motor failed. Be sure you have hydraulic flow to the motor. If oil
flow to motor is good, but motor will still not turn when detached from trencher
headshaft, remove motor and have it serviced or replaced as needed.
7. Headshaft bearings failed. Inspect headshaft bearings for free movement.
Check for binding or foreign matter jamming bearing. Clean or replace as
necessary.
8. Boom end bearing failed. Inspect boom end bearing for free movement.
Check for binding or foreign matter jamming bearing. Clean or replace as
necessary.
