this product.
SAVE THESE INSTRUCTIONS!

WARNING:

• Risk of personal injury. This gun is capable of developing over 10,000 psi pressure. Do not
expose skin to potential rupture sites or end of grease coupler. User should wear safety
goggles while operating. Only extensions and couplers rated for this pressure are
acceptable to use. If grease injection occurs, seek immediate medical attention. Do not
attempt to treat the injury yourself.
• Do not attempt to remove the inlet valve or the internal piston assembly. Reassembly of these
components must be performed by trained service technicians to prevent damage. Other attempts
to repair or modify will void warranty.

OPERATION:

• The switch must be set to "Volume" mode in order to properly prime the gun.
• The handle must be in the full open position to switch from "Volume" mode to "Boost" mode. Always
allow the handle to fully retract before switching between modes.
• Switching from "Volume" to "Boost" mode will result in a 4:1 increase in pressure for the same
grip force. The volume delivered will be decreased to approximately one-fourth while in "Boost"
mode. After unblocking the obstruction, switch back to "Volume" mode for normal delivery
(22 strokes / ounce).
• When full stroke of the handle is not possible due to limited space, partial strokes may be used to
deliver grease at proportionally lower displacement per stroke.
• The Air-Pocket Valve may be used to expel air pockets from the head of the gun. Air pockets will
prevent priming.
