Adjusting Plunger Rod
1.
To manually adjust plunger rod, press
in and hold rod release trigger.
2.
Grasp plunger rod handle and either
push or pull rod in or out.
3.
Release rod release trigger.
NOTE:
Keep plunger rod clean of material.
Retracting a plunger that is covered with
material may damage the internal parts of
the tool.
Electronic Overload Protection
The gun is protected by an electronic over-
load protection feature. If too much pres-
sure is exerted on the tube, the motor will
automatically reverse for one second, and
then shut down. This helps to prevent dam-
age to the tool and the caulk tube or pack.
If the motor shuts off, make sure that:
•
Nozzle tip is cut
•
Inner seal in the caulk tube is broken
•
Hardened material is removed from the
nozzle
•
Caulk tube is not damaged or frozen
•
Plunger rod is free of caulk/adhesive
materials
Release trigger to allow the electronics to
reset. If the motor continues to shut off, try
another tube of material or take the tool to
a
MILWAUKEE Service Center.
Auto-Reverse Mechanism
This tool has an auto-reverse feature that
reverses the plunger when the trigger is
pressed for more than 2 seconds and
released. This feature helps stop excess
material from continuing to flow.
Pulsing the trigger will deactivate the auto-
reverse mechanism and allow for contin-
ued pressure on the tube. This helps main-
tain a slower material feed rate.
Auto-Shut Off
When a caulk tube is empty, the auto-shut
off feature will turn the motor off. Pull the
plunger back and replace the tube.
Caution:
Unexplained tool shut-off or
auto-reverse may be due to caulk or adhe-
sive material on the plunger rod. Plunger
rod must remain clean and free of all caulk
and adhesive material. If material does get
on plunger rod mechanism, remove the
plunger rod and clean the material off of
the rod and tool with a brush and solvent
according to the caulk or adhesive material's
manufacturer.
