LINEAR ACTUATOR TROUBLESHOOTING, REPAIR KITS AND INSTALLATION INSTRUcnONS

FOR 8-4225 ELECfRIC LIFT KIT

General: The chart below will be helpful for isolating malfunctions in the control system, countering difficulties' with system start-up, and in troubleshooting for worn or broken mechanical or electrical components in units which have been operating for some time. For correct diagnosis it is important to do all tests before disassembling the actuator.

Symptom: Actuator will not extend/retract

Checkpoint

No voltage or amp draw

Proper voltage, no amp draw

Proper voltage, amp draw present, clutch not slipping

Proper voltage, amp draw present, clutch slips

Probable Cause Possible Solution

Actuator not receiving power Check power supply ------------------

Dead motor Replace motor

Thermal overlaod cut-out Let cool, check duty (when overheated) cycle

Excessive shock loads or vibration throughout life of actuator

Actuator overloaded

Clutch worn too low (Excessive ratcheting)

Check for possible stripped gears

Check rated load

Replace clutch

I Symptom: Actuator stops In mid-stroke

Checkpoint

Clutch slips

Clutch doesn't slip, no amps

Clutch doesn't slip, amps present

Probable Cause

Actuator overloaded

Blown fuse

Thermal cut-out

Motor stalled

Symptom: Actuator does not hold position

Checkpoint

Actuator will not extend or retract

Probable Cause

Excessive shock loads or vibration throughout life of actuator

Possible Solution

Check rated load

Replace fuse

Let cool, check duty cycle

Check voltage (too low)

Possible Solution

Check for possible stripped gears

At this point remove actuator from the mechanism to run by itself. Watch and listen for any changes in behavior.

Replacement parts are available for Warner Electric linear actuators in kit form, through WHEEL HORSE parts distribution. Description of kits, installation instructions, diagrams and part numbers are included below.

REPAIR KIT INSTALLATION

NOTE: All screws can be replaced with standard machine screws (#12-24 and #10-32). Tighten all screws/nuts to 70 in-Ibs upon reassembly (except single screw in rear housing - tightened to 20 in-Ibs).

NOTE: GREASE - Rear Housing is packed approximately half full with Mobilplex #47 grease. Also, a bead of this grease has been placed on Drive Screw. When servicing these areas equivalent lubricant (Calcium base E.P. Multi-purpose grease) must be present for proper operation of actuator.
