IMPORTANT:
Read all instructions and warnings before operating this product.
SAVE THESE INSTRUCTIONS! READ ALL INSTRUCTIONS!
WARNING:
• 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.
OPERATIONTIPS:
• When full stroke of the handle is not possible due to limited space, variable (short) strokes may
be used to deliver grease at proportionally lower displacement per stroke.
• The Automatic bleeder will expel air pockets when reconnecting the barrel and head, this will
greatly reduce air locks and priming problems.
IMPORTANT: Do not load gun with air-operated grease pump. Damage to unit will occur and
warranty will be voided.

a. Always push Lock-n-Load™ switch forward as far as possible.
b. Grease cartridge is not inserted completely into barrel.
c. Excess grease maybe in head
- Remove excess grease.
d. Auto bleeder maybe plugged
3. Grease does not flow when handle is stroked:
a. Release follower rod and push up if it doesn’t automatically go up.
b. Grease cartridge maybe empty.
b. See best practices, priming after refilling with grease.
4. Boost Mode, High Pressure not achieved:
a. Release follower rod and push up if it doesn’t automatically go up.
b. Barrel may be empty.
c. See best practices, priming after refilling with grease.
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).
