Problem
Possibilities
Solution (see “How to”)
How to
Saw will not
raise, or
rises slowly out
of the cut
Pump pressure set too low
Low hydraulic oil/leaking oil
Bad lift pump
Increase pump pressure
Replace lift pump
Call service for support
Pump pressure can be increased or decreased
by adjusting the pressure relief setting located
on the pump manifold. Make small adjustments
and recheck - Add blade guard(s) to the front of
the saw for extra load weight.
Loss of 12v power supply
Check connections to the solenoid
Check ground connection to the pump
Check connections at the battery posts
Check solenoid
Check battery charge
Make sure there are no cracks or breaks in the
copper solenoid bracket, and battery posts/
conections are tight and free of debris.
Test solenoid using a multimeter or
other device, check the battery for
proper voltage.
Hydraulic oil leak or low oil level
Check fittings and hoses for leaks, and
check oil level in reservoir
Inspect the fittings, connections and along the
hose routing for oil leaks and seepage.
Note:
always support the weight of the saw
when working with a raised hydraulic system
(under pressure). Reservior contains 1 qt of ATF.
Standard (Mechanical lever)
models- valve is partially
open when lever is in the
closed position
Make sure red lever (under control
panel) is in the closed position
Review Raise/Lower instruction sheet,
call service for assistance
Remove the rear panel to access the red
lever. Loosen the 5/16 bolt and nut holding
the red lever to the main body assembly. Push
red lever forward until the valve has reseated.
Tighten bolt and nut on red lever to secure to
main body.
Button Style models
(electric version) - dump valve
bypass is stuck open
Replace valve
Lower the saw completely to relieve all pressure
in the valve and system. Locate the valve from
the manifold and replace. See technical sheets.
Faulty check-valve in the pump
manifold
Remove check-valve and inspect for
debris that may cause stuck valve or
faulty spring
Lower the saw completely to relieve all pressure
in the valve and system. Remove the raise
control valve and fitting to expose the
check-valve inside of the pump manifold. Using
a 3/8 allen wrench, turn clockwise and remove
set screw. Visually inspect for debris.
Compressed air may be used to clear.
See technical sheets.
