Operation
Product Description
Shown with optional trigger guard
Thank you for purchasing either a Macnaught Model
B2 or B2-SG Booster Gun.
The Macnaught B2 Booster Gun is a high pressure
hose end dispensing gun designed for use with air
operated greasing systems such as the Macnaught
Powerlube and Maxilube model grease pumps.
The Booster Gun includes a 360 deg Z swivel
assembly and incorporates a booster mechanism
which allows the user to boost the greasing
pressure up to 69MPa / 10,000 psi / 690 Bar when
required.
1) Ensure that the gun coupler is securely positioned
onto the grease nipple (zerk).
2) Squeeze the trigger mechanism to allow grease to
be dispensed into the grease nipple (zerk).
3) If no grease flows because of a seized nipple
(zerk), pull the trigger several times. Each squeeze
of the trigger increases (boosts) the greasing
pressure until grease flows.
Disconnect the air supply before servicing
Grease is being dispensed at high pressure.
Keep your hands away from the nipple (zerk) /
coupler connection at all times.
CAUTION
4) To remove the coupler from the nipple (zerk), tilt
the gun to relieve the pressure and then twist and
pull the gun to disconnect from the nipple (zerk).
