Troubleshooting

Problem Cause Solution

Too much grease at all lube points Timer cycle too frequent Adjust the timer one click to a higher time

cycle. (Example, from 2 to 3 hours.)

Too much grease at one lube point Meter leaking Remove and replace meter

Not enough grease at all lube

points

Timer cycle is too infrequent Adjust the timer one click to a lower time

cycle. (Example, from 3 to 2 hours.)

No sign of fresh grease at all points Lubricant reservoir filled with

heavy grease which will not

work in system.

Remove and clean reservoir, refill with

proper lubricant. Remove main line plugs

from meter blocks, and cycle pump until old

lubricant is removed from lines, replace

main line plugs.

Blown fuse, or break in wiring

circuit

Check for electrical short circuit or broken

wire, and repair.

Broken air line (air pump only) Repair or replace line.

Inoperative solenoid air valve

(Air pump only)

Check electrical circuit to make sure volt-

age is reaching the solenoid coil from the

timer. Connect a meter from the supply

“black” wire to the return “white” wire at the

connector of the solenoid. Do not connect

direct to ground. Repair or replace wiring

as required: Check coil resistance for

approx. 20 ohms. Check valve operation;

repair or replace if necessary.

Inoperative air pump

See Troubleshooting, Air-operated pump

not working, page 18.

Inoperative electric pump See Troubleshooting, Electrically operated

pump not working, page 18.
