Solution
Check cord to make sure fan has power
Clear debris from fan/fan grill
Try to stop fan by lightly pressing on the center with a
pencil eraser. If the fan slows down easily it will need
to be replaced
Move machine to an area below 120°F
Check cord to make sure fan has power
clear debris from fan/fan grill
Try to stop fan by lightly pressing on the center with a
pencil eraser. If the fan slows down easily it will need
to be replaced
Move machine to an area below 120°F
Reset coupler per specifications and retighten set
screws
Check cord to make sure fan has power
Clear debris from fan/fan grill
Try to stop fan by lightly pressing on the center with a
pencil eraser. If the fan slows down easily it will need
to be replaced
Check cord to make sure fan has power
Clear debris from fan/fan grill
Try to stop fan by lightly pressing on the center with a
pencil eraser. If the fan slows down easily it will need
to be replaced
Check oil level and if low add more hydraulic fluid
Check to ensure the hydraulic oil level sensor is
properly connected to the MCM and that the wire has
not been damaged
Replace sensor
Inspect hydraulic driver end seals and early leak
detection tubing. Replace seals as necessary and
replace lost oil.
Inspect the hydraulic reservoir fittings and filter for
leaks. Repair or replace as necessary and replace
lost oil.
Replace motor
Check wiring to the motor to ensure no bare wires are
touching and that no wires are shorted to ground
Check wiring to the motor to ensure no bare wires are
touching and that no wires are shorted to ground
Unplug the directional valve (so pressure will not
build) and try to move the motor again. If this
succeeds then the power pack may need to be
replaced. If the motor is still unable to move, the
bearings or hydraulic pump have likely failed in the
motor and will need to be replaced.
Make sure the supply line is properly sized for the
load and is above the minimum voltage requirements
Check for MCM software update, load latest MCM
software, if problem persists contact Graco
