Automatic Shut off
When the caulk tube is empty an internal
limit switch will turn the motor off.
Replace the tube. The caulk gun will not
start again until the plunger is pushed back,
even if the switch is turned on.
WARNING!
When caulk gun is not in use, lock
the trigger to prevent the caulk
gun from being
accidentally.
Plunger Attachment
Caulk tubes vary in size and design so this
caulk gun is equipped with a removable
plunger extension.
1. If the clutch ratchets when the caulk
tube is empty, remove the plunger ex-
tension from the plunger.
2. If the automatic shut off stops the
plunger while there is material remain-
ing in the caulk tube, make sure that
the plunger extension is mounted to
the plunger.
NOTE: Keep plunger clean of caulk mate-
rial. Retracting a plunger that is covered
with caulk material will damage the internal
parts of the gun.
Material Level Indicator
The white portion shows how much caulk
material remains. When the display is or-
ange, the tube is empty.
