Sharp blades may cause cut injury!
For proper protection of hands, a protective glove
should be used when operating this equipment and
during the handling of blades.
Always disconnect the tool from the air supply prior
to servicing.
Blade Removal - Large Tools
Models: 750, 850, 1000, 1300, 1400, 1500, 1850, 1880
Hold the tool in your hand.
Loosen only the left cover retaining screw
(Item #1).
With a screwdriver held in the opposite hand,
insert the screwdriver in the housing slot
(Item #2). Using the frame as the support
point (Item #3), spread open the housing. The
blade should fall out.
NOTE: Some tools have 2 slots in the housing.
NOTE:
A slight tension on the left cover screw will
allow the blade housing to stay open on its own.
Blade Installation - Large Tools
Models: 750, 850, 1000, 1300, 1400, 1500,
1850, 1880
Turn the tool over so the blade side is up.
Spread open the blade housing with a screwdriver.
NOTE:
A slight tension on the left cover screw will allow the blade housing to stay open on its
own.
Insert a new blade in the housing.
Loosen the left cover retaining screw so the housing will close.
Adjust the housing for proper running clearance. The blade should turn freely with a
slight side-to-side motion. This leaves room for the grease.
WARNING!
Make certain that the blade is free to rotate in the housing. If the blade does not
turn freely, it may cause the tool to rotate in the hand.
Tighten the left cover screw to 35 in-lb. (4 N-m). Use of the Bettcher torque wrench kit is
recommended.
Re-check the running clearance.
