Installing and Removing Blades


CAUTION: Cut Hazard. Blade tension lever is under
spring pressure. Maintain control of lever when
releasing blade tension.
To Install Blade (Fig. A, D–F)
1. Rotate the blade tension lever
until it stops to release tension on blade (refer to
Figure A).
2. Turn the saw over and place it on a workbench or table.
3. Unlatch the two blade guard latches
blade guard.
4. Position the blade so that the teeth face out from the
saw and cut towards the work stop
blade direction
5. Slip blade into the guide rollers
pulleys 18 as shown in Figure D.
6. Make sure that the blade is fully inserted into the guide
rollers and positioned fully on the rubber tires
just touching the rear guide bearings
7. Rotate the blade tension lever
it stops and then close blade guard and secure latches.
Make sure the teeth face away from the band saw
(Fig. A, D).
8. Turn the saw on and off a few times to ensure that the
blade is seated properly.
To Remove Blade (Fig. A, D–G)
1. Rotate the blade tension lever
until it stops to release tension in blade (refer to
Figure A).
2. Turn the saw over and place it on a workbench or table.
3. Unlatch the two blade guard latches and open the
blade guard.
4. When removing the blade, tension may be released and
the blade may spring free. SAW BLADES ARE SHARP. USE
CARE IN HANDLING THEM.
5. Inspect the guide rollers
which may be lodged in them. Lodged chips can prevent
rotation of the guide rollers and cause flat spots on the
guide rollers.
6. Rubber tires 20 are mounted on the pulleys
rubber tires should be inspected for looseness or damage
when changing the blade. Wipe any chips from the
rubber tires on the pulleys with a brush.
nOTE: Do not use your hands to wipe chips.
This will extend tire life and keep the blade from slipping.
If any looseness or damage occurs, the tool should be
brought to an authorized D
repair or replacement as soon as possible. Continued use

Blade Tracking (Fig. A, F, G)

WARNING: To reduce the risk of serious personal
injury, turn tool off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start‑up can cause injury.
NOTICE: Excessive tightening of the adjustment screws
could result in damage to the saw.
Your band saw is equipped with an adjustable blade tracking
mechanism which assures proper blade tracking at all times.
The blade is properly adjusted when it is sitting fully on
rubber tires

To Adjust the Blade Tracking
1. Turn and open the blade tension lever
to the tracking screw
2. Use a 10 mm wrench to loosen the locking nut
(Fig. G).
3. Use a 3 mm hex wrench
and 1/4 turn clockwise or counterclockwise (Fig. G).
nOTE: Turning the tracking screw clockwise moves
the blade toward the guide roller, turning the tracking
screw counterclockwise moves the blade away from the
guide roller.
4. Tighten the locking nut and close the blade tension lever
and blade guard. (It will be necessary to run the saw to
observe the tracking.)
5. Observe blade tracking between runs and repeat Steps
1–4 as necessary to achieve proper blade tracking.
Blades
This portable band saw is setup for use with .02"
(0.5 mm) thick, 1/2" (12.7 mm) wide and 27" – 27-1/4"
(686 mm–692 mm) long blades. DO nOT use .025"
(0.64 mm) thick blades.

WARNING: The use of any other blade or accessory
might be hazardous. DO NOT use any other type
of accessory with your band saw. Blades used on
stationary band saws are of different thickness. Do not
attempt to use them on your portable unit.

Blade Selection

In general, first consider the size and shape of the work,
and the type of material to be cut. Remember, for the most
efficient cutting, the coarsest tooth blade possible should be
used in a given application, because the coarser the tooth,
the faster the cut. In selecting the appropriate number of
teeth per inch of the band saw blade, at least two teeth
should contact the work surface when the blade is rested
against the workpiece. As a rule of thumb, soft materials
usually require coarse tooth blades, while hard materials
require fine tooth blades. Where a smoother finish is
important, select one of the finer tooth blades.
