POSSIBLE CAUSES
TROUBLE: Timer Turns On At Intervals Two (2) To Ten (10) Times More Often Than Set Time Interval:
Electrical noise is being introduced into the power
supply to the timer overcoming suppressor capacitor
causing uncontrolled turn-on of its output relay.
TROUBLE: Timer Turns On At Intervals Faster Than Allowable Tolerances Of Settings:
Timer out of adjustment or damaged component.
Reservoir Fill Procedure
Lubricant Required for System
Refer to ''Lubrication Chart'', for correct lubricant speci-
fications.
• . Above 90°F (32°C) - Use NLGI No.2 multipurpose
grease (MPG).
• . -25° to 90°F (-32° to 32°C) - Use NGLI No. 1 MPG.
• . Below -25°F (-32°C) - Refer to local supplier for
extreme cold weather lubricant requirements.
Fill Procedure
1. Remove top vent plug (14, Figure 4-12).
2. Remove bottom fill plug (15).
3. Connect line from Lubricant Delivery system to
bottom fill port (15) and fill reservoir until grease
just begins to come out of top vent hole above.
4. Disconnect line from Lubricant Delivery system
and install plugs (14 & 15) previously removed.
SUGGESTED CORRECTIVE ACTION
IMPORTANT: In some instances, electrical noise
may be generated into vehicle electrical system
which may cause timer to turn on at random inter-
vals, independent of timer setting.
If this occurs, a 250 to 1,000 MFD capacitor rated
150 to 350 VDC should be added across BAT (+ )
and BAT (-) terminals to suppress this noise and
improve timer performance.
Refer to ''Timer Adjustment and re-adjust timer, or
replace timer.
