Troubleshooting
CAUTION
Follow referenced procedures when correcting
faults. Observe all CAUTIONS and WARNINGS.
The function and performance of this device is highly
dependent upon proper installation and setup.
If the BreakerLube CML fails to work properly and the
cause cannot be determined from the troubleshooting
table below, contact Allied’s Technical Service
Department for further assistance.
Fault
Possible Cause
Remedy
Pump fails to run
Power supply
interrupted
Check fuse and voltage at power supply. The motor voltage
and supply voltage must match.
Mechanical bind
prevents motor rotation
Clear obstruction
Pump running, but
lubrication fails to
reach discharge point
Reservoir is empty
Fill Reservoir with chisel paste. Trigger a lube cycle and allow
pump to operate until grease dispenses from lubrication point.
Blockage
Impurities in grease. Damaged lube lines. By-pass at relief
valve. Vent on reservoir is blocked.
Formation of air pocket
Disconnect line at pump and run pump until solid flow of
grease is verified. Next bleed air from lines with grease gun
attached to lube fitting on relief valve.
Lube line replaced but
not pre-filled
Pre-fill line using grease gun. Do not attempt pre-fill with pump.
Pump running, but
delivery output at
discharge point is low
Cold temperature.
Check NLGI number of grease. Pumpability of selected grease
is too high. At cold temperatures lubricant it may take up to 10
minutes of operation before the pump elements reach their full
output.
Restriction in line
Clear impurities. Locate source of contamination and
eliminate.
Line size is too small. Kinked or crushed hose.
By-pass
Bypass at relief valve or piston. Check valve inside pump
element not closing.
Worn parts
Inspect piston, check valve and spring for wear.
Formation of air
pockets or
contamination
Incorrect re-filling
method
Re-fill reservoir with clean grease at fitting located on pump
housing. Pre-fill replacement lines. Keep lid on reservoir. Store
grease properly. Do not use contaminated grease or grease
that has changed consistency over time. Wipe grease fitting
before attaching grease gun.
Pumpability is the ability of grease to be pushed
through passages until it is distributed at points
where the lubrication is needed. Pumpability, in terms
related to grease-dispensing systems and their use
with breakers, is defined as the ease with which
grease can flow through hoses, fittings and passages
that lead to the front head and bushings.
Pumpability becomes increasingly difficult at colder
temperatures. If the system is to be used in
temperatures below freezing, a cold weather paste
must be used. In such cases, please contact Allied's
Technical Service Department for recommended cold
weather pastes.
The use of Allied Chisel Paste is recommended for all
Allied breakers. Allied Chisel Paste can be used in a
temperature range of 32º F to 122º F (0º C to 50º C).
