TROUBLESHOOTING
The following contains general troubleshooting problems and solutions for Merit at saws, please
refer to the Owner’s Manual that is specic to your saw. If you do not have a manual or do not know the
model of your saw, please check the ID Plate located in the lower rear control panel near the battery.
For additional questions, or to request a copy of the Owner’s Manual,
please email: [e-mail].
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 ttings and hoses for leaks, and
check oil level in reservoir
Inspect the ttings, 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 tting 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.

Rev 12.17.19
Problem Possibilities Solution (see “How to”) How to
Engine
overheating
Cooling fan
won’t come on
Blown fuse Check fuse in wire harness (40A) Check wire harness directly from the fan to the
battery. Remove fuse and visually inspect.
Bad temperature sensor Bypass (jump) sensor - trigger point is
180 degrees F
The temp sensor provides a ground to the fan.
With the key in the “on” position, test by using a
jumper wire from any solid ground point to the
sensor.
Caution: ensure fan and fan blades are clear, fan
may start up with this procedure.
Bad relay Replace relay Ensure the relay has proper ground and voltage.
Replace relay if issue persists.
Loss of 12v power supply
Inspect wire harness and post
connections, corrosion should not be
present on any terminals
Make sure there are no cracks or breaks in the
copper solenoid bracket, and battery
posts/connections are tight and free of debris.
Test solenoid using a multimeter or other device,
check the batter for proper voltage.
Engine
overheating
Mechanical fan
turning slow or
not turning
Loose belt Tighten belt Locate the blue tensioner - adjust tension per
techinical sheet.
Broken belt Replace belt See parts manual for required parts.
No belt Replace belt See parts manual for required parts.
Broken right angle shaft Replace right angle drive box See parts manual for required parts
(additional parts may be required).
Worn fan blades (damaged) Replace fan See parts manual for required parts
(ensure correct fan orientation).
Saw won’t roll
in “o “ position Dierential is locked Pull dierential cable to the neutral
position
The dierential cable should be pulled into
neutral and twist to lock lever in position.
Positraction is
locked
Positraction will not disengage Release the positraction cable Push "Pull" cable down to disengage.
Concrete slurry build-up Ensure the shift fork spring releases
Pulling the fork may be required to release the
spring. Channel locks or pliers may be needed.
Lubricate with oil or WD-40.

Rev 12.17.19
Problem Possibilities Solution (see “How to”) How to
Saw won’t start
Emergency stop engaged Disengage emergency stop Pull and twist to disengage.
Contact blocks damaged Inspect contact blocks and
connections
Remove contact blocks from panel, inspect
for continuity.
Dead battery Have battery tested Use multimeter, or have tested.
Loose cables
Ensure clamps are clean and tight -
check power and ground on engine
connections
Inspect clamps and clean if necessary,
visually inspect power and ground
connections on the engine.
Bad starter Have starter electrically inspected Remove starter and have tested.
Bad ignition switch Inspect using multimeter or replace
switch
Check for continuity and conectivity.
Replace if necessary.
ECU connections Visually inspect pins for corrosion -
replace ECU if issue persists
Remove main plug - ensure all pins are
clean and seated (not bent or missing).
Low/no fuel Inspect fuel tank (not guage) for fuel Remove fuel cap and visually inspect inside
of the fuel tank.
Fuel pump Check voltage. Replace if voltage is
supplied and does not engage Turn key on, fuel pump has audible sound.
Clogged/dirty fuel lter Inspect fuel lter / replace if neccesary Clean lter housing to visually inspect fuel ow.
