Westward Operating Instructions
WORKING OF PUMP
The pump has a spring loaded wave action mechanism
installed at the bottom of the bucket.
Pressing the foot lever
makes a cylinder to move
forward leaving empty
space behind it. The
grease due to its
weight fills this empty
space.
Cylinder in open position
On releasing the foot lever,
the cylinder returns to its
original position pushing
the accumulated grease
into a hollow piston that
throws the grease from
the pump outlet into
delivery hose.
Cylinder in closed position
Subsequent strokes of the foot lever fill the delivery hose
& discharge begins from the pistol handle.

OPERATION & USE
1. Fill correct grade grease into the pump bucket.
2. Tamp the bucket on a firm surface to push the
grease to displace air pockets trapped in the cavities
in the base of the bucket.
3. Operate the pump by pressing the foot lever a few
times until delivery commences.
4. Now the pump is ready for dispensing. When not
in use, the pistol handle can be put into the nozzle
holder provided at the side of the foot lever.
PRIMING THE PUMP
Priming is getting the pump started by operating foot
lever for 3-4 minutes until grease gets dispensed
from the the pistol handle. Foot operated pumps are
difficult to prime for the first time. It takes many
strokes to get the pump working and hence pump is
supplied in a Pre Primed condition. Pump will have
some grease as pre priming leaves certain amount
of grease in the system.
When working in cold weather or using a
thicker grease, keep grease thin for easy
workability in one of the following ways:
• Mix some oil (SAE30) with grease. Shake
the bucket & press the mixture thorough-
ly to remove any air pockets
• Heat grease bucket with a Barrel Warmer
or Heating Jacket. The temperature
should be kept at 0 - 30°C (32 - 86°F)
• Keep work area clean and remove any excess
grease from tools, hands, and clothing after use
• The user may need to warm grease in cold
weather. NEVER overheat grease as it may loose
its lubricating properties
• This pump is not a Food Grade product
