ATTACHING THE STORAGE BRACKETS
The MI-91520 is equipped with onboard storage
brackets to store the rip fence and miter gauge
when not in use. Attach the rip fence storage
bracket and miter gauge storage brackets to the
back of the saw as shown in Figures 5 and 6, us-
ing the bolts and washers already mounted to the
saw.
ATTACHING THE TABLE
The worktable mounts on a bracket.
This bracket can adjust from 0° to 45°
to the right. These adjustments are easy
to make with the angle scale and lock
knobs.
1. Remove the RED INSERT (A) from
the centre of the table and the
TABLE ALIGNMENT PIN (B) from
the table slot. See Figure 7.
2. Turn the table right side up.Verify
that the LONG BOLTS (C) in the
centre of each trunnion are pointing down. See Figure 8.
3. Carefully position the table over the TABLE”TILT BRACKET (D), guiding the saw
blade through the TABLE SLOT (E). See Figures 9 and 10.
Note: If the long bolts have moved out of position, have an assistant tap them into place with a
screw driver.

that the saw blade is now perpendicular to the
TABLE SLOT (F). See Figure 11.
5. Gently lower the table onto the bracket so
the LONG BOLTS (C) in the centre of the
trunnlons pass through the holes in the
TABLE-TILT BRACKET (G). See Figure 12.
6. Tread the two small LOCK KNOBS (H) onto the
LON! BOLTS (I) now protruding from the
underside of the tabletilt bracket and tighten
carefully. See Figure 13.
7. Attach the TABLE TILT SUPPORT BRACKET
(J) to the rear of the saw using the BIG LOCK
KNOB (K) with the two FLAT WASHERS (L)
already mounted on the frame. See Figure 14.
8. Make sure that the blade is centered in the
TABLE OPENING (M). If the blade is not
centered, slide the table back or forward until
the blade is centered in the table opening. Then
fully tighten the two LOCK KNOBS (H). See
Figure 15.
9. Reinstall the insert into the centre of the table,
with the opening in the SLOT (O) facing the

INSTALLING THE FENCE ASSEMBLY
This band saw is equipped with a foot brake locat-
ed at the bottom of the machine. The foot brake
allows for immediate immobilization of the blade
1. Open the lower wheel cover door.
2. Attach the foot brake to the FOOT BRAKE
MOUNTING BAR (Q) using the two supplied CAP
SCREWS AND LOCK WASHERS (R), in the as-
sembly order shown in Figure 20.
3. Firmly tighten with the supplied 8 mm Allen key.
The foot brake is not designed to function as the
primary stop mechanism of this saw. The foot
brake should be used for emergency situations or
any time it is necessary to immobilize the blade
quicker than normal. Under normal working condi-
tions the red stop button should be used as the
primary stop mechanism. Continuously using the
foot brake as the primary stop mechanism can
lead to premature wear of the brake and may
cause damage to the motor.
WARNING!
This tool is for indoor use only. Do not
expose to rain or use in wet or damp
locations.

WARNING!
To avoid injury, ensure the power switch is OFF and the power cord is unplugged before adjusting the band saw.
ADJUSTING BLADE GUARD
The BLADE GUARD (A) can be adjusted to accommodate
the height of the workpiece. To prevent the blade (which is
fexible and which would not otherwise be supported) from
slipping out of position during cutting, and to reduce risks of
injuries, expose a minimum amount of blade.
The blade guard should be set 1/8” to 1/4” above the work-
To adjust the height of the blade guard
is disconnected from the power source.
2. Loosen the LOCK KNOB (B). See Figure 42.
3. Move the blade guide assembly up or down by turning
the HAND WHEEL (C). Then re-tighten the lock knob C.
The DEPTH GAUGE (D) on the blade guard can be used as
a reference but it is not intended for precise measurements.
See Figure 43.

MAINTENANCE
MAGNUM INDUSTRIAL MI-91520 DELUXE 14” BAND SAW
WARNING!
Always disconnect the machine from the power source before performing any lubrication or maintenance.
WARNING!
If any part is damaged, do not use the band saw. Replace
any damaged part as soon as you notice the damage.
WARNING!
To avoid eye injury from blowing debris, wear safety
goggles when blowing out sawdust.
PERIODIC MAINTENANCE and LUBRICATION
Lubrication
Keep the RACK AND PINION (A), BLADE TENSION AD-
JUSTMENT SCREW (B), and the TABLE TRUNNION (C)
well greased and free of dust and debris.
Clean and remove dust, debris and old grease after every
10 to 15 hours of use. After cleaning, re-apply grease as
needed. Use any all-purpose grease.
The motor and all bearings are sealed and permanently lu-
bricated. They require no further lubrication. No other part of
this band saw needs lubrication.
PERIODIC MAINTENANCE
not operate the band saw with a damaged switch. Replace
a damaged switch immediately.
damage.
blow out or vacuum up the sawdust and wipe down the
machine occasionally with a damp rag.
Keep the band saw wheels and tires clean. Dirt and debris
on the wheels can cause the blade to slip.
blade, guide and thrust bearings. Clean as needed with
gum and pitch remover. But do not immerse the bearings
in gum and pitch remover.
To prevent rust from forming on the unpainted cast iron of
the table, and so that the wood slides easily while cutting,
apply a light coating of paste wax or use regular
applications of any aftermarket surface protectant or rust
inhibitor.
