PUMPING LUBRICANTS (Refer to Figure 2-28.)
NOTE
The engine-oil, grease and gear-lube pumps pump lubricants from the lube tank.
The lube tank is divided into three compartments: one for engine-oil, one for
grease, and one for gear-lube. Before dispensing any of these lubricants, you
must first prime the lubricant pump(s).
(1)
To prime low pressure pumps (1) or high pressure pump (2), open the recirculation valve (3) that
corresponds to the pump that you want to use.
(2)
Let the air pressure slowly increase until the pump starts cycling.
(3)
Allow the pump to cycle for a few minutes or until you know all air is expelled from the lube tank (4) and
system, by opening the manhole cover (5). You can see the pumps cycling and expelling air.
(4)
Increase the air pressure as necessary. (Maximum of 100 psi for low pressure pumps (1) and maximum of
200 psi for high pressure pump (2).
(5)
As soon as pumps are primed, turn off the recirculation valve (3).
NOTE
To dispense lubricant, first determine which lubricant you need. The lubricant
types are labeled on the front of the reel cabinet assembly from left to right as
follows: gear lube, grease, air, grease, and engine-oil.
(6)
Pick up the control valve (6) that you need. It should be resting on control valve holder (7)
(7)
Allow the reel (8) to spin freely by releasing the hose reel lock (9).
(8)
Pull out the desired amount of hose, determine quantity of lubricant needed, and If dispensing gear lube or
engine oil, set the meter on the control valve (6) accordingly.
(9)
Begin pumping by holding down the handle (10).
(10)
Finish lubricating; then roll up the hose, set the hose reel lock (9), and lay the control valve on control valve
holder (7).
