Installation
Place unit in approximate location,
make sure that electric and hydraulic
power connections are accessible
1 Mark center locations of four holes at
bottom of reservoir
2 Drill four
5
/
in (15 mm) holes
8
Use of
1
/
in (12 mm) bolts will offer
2
some flexibility in securing reservoir
to equipment
3 Connect lubricant outlet of pump to
system with suitable hose capable of
3 500 psi (241 bar) working pressure
Hydraulic inlet connection should be
made with at least
3
/
in (9 mm) inner
8
diameter hose capable of at least
3 000 psi (207 bar) operating pressure
Hydraulic return to tank connection
line should be
3
/
in (19 mm) inner
4
diameter hose or pipe
Refer to manual 404554 for setting
pump pressure and flow control
Operation
Fill reservoir
1 Clean area around filling port
2 Remove pipe plug (17) from side
of reservoir
3 Attach appropriate bulk-filling pump
to lower inlet (1 in NPT)
4 Fill reservoir until level sensor
indicates that reservoir is full
5 Remove bulk filling pump
6 Replace pipe plug
Fill reservoir
(MSO equipped)
Body and guide assembly (73), pivot
arm assembly (72), supply line relief,
follower assembly (35) and drum
cover (14) work in combination with
each other to prevent grease from
overfilling reservoir during refill process
(→ Fig. IPB 1, page 15)
As grease fills reservoir, follower rises
and lifts pivot arm, forcing body and
guide assembly closed When body and
guide assembly closes, pressure
continues to rise in supply line causing
pump to stall At that point, supply line
relief valve must be opened to relieve
pressure from system
Operational
procedure
1 Verify relief valve is closed
2 Turn supply pump on
3 Supply pump stalls when gauge
reaches maximum
4 If grease level sensor or indicator
option is available with system, verify
reservoir is full of grease
5 Turn off supply pump
6 Open pressure relief valve to vent
down stall pressure Make sure relief
valve is open long enough to remove
pressure form system
7 Disengage quick disconnect
8 Cap quick disconnect ends to prevent
contamination
9 Leave relief valve open until next fill
cycle

Maintenance
• Keep area around pump clean Clean
off filling port area prior to filling
reservoir Clean area around filler after
filling as lubricants will attract dirt
• Keep lubricants clean and free of dirt
and debris
• When replacing grease pails prevent
any foreign matter from entering
grease pail or contaminating grease,
as it adheres to pump
