1.0 IMPORTANT SAFETY

INSTRUCTIONS

WARNING – To reduce risk of injury:

1. Read and understand the entire owner's
manual before attempting assembly or
operation.

2. Read and understand the warnings posted on
the machine and in this manual. Failure to
comply with all of these warnings may cause
serious injury.

3. Replace the warning labels if they become
obscured or removed.

4. This band saw is designed and intended for use
by properly trained and experienced personnel
only. If you are not familiar with the proper and
safe operation of a band saw, do not use until
proper training and knowledge have been
obtained.

5. Do not use this band saw for other than its
intended use. If used for other purposes, JET
disclaims any real or implied warranty and holds
itself harmless from any injury that may result
from that use.

6. Always wear ANSI Z87.1 approved safety
glasses or face shield while using this band
saw. (Everyday eyeglasses only have impact
resistant lenses; they are not safety glasses.)

7. Before operating this machine, remove tie,
rings, watches and other jewelry, and roll
sleeves up past the elbows. Do not wear loose
clothing. Confine long hair. Non-slip footwear or
anti-skid floor strips are recommended. Do not

Read and understand all

assembly instructions before attempting
assembly. Failure to comply may cause serious
injury.

5.0 Setup and assembly

Disconnect band saw from

power during setup.

5.1 Shipping contents

5. Adjust leveling screws until machine is level in
both directions and tighten nuts against the
base flanges.

6. Install material stop into front hole in table, as
shown in Figure 7-9.

7. Fill coolant reservoir with 15L (4 gal.) of
appropriate coolant, by pouring it through the
filter screen atop the pan.

8. Install splash plate over lip of base and below
cutting area. This deflects coolant and chips
down into the base.

1 Band saw
1 Splash plate
1 Tool box containing:
6 Leveling pads
1 Set of open-end wrenches
1 Set of hex wrenches
1 Cross-point screwdriver
1 Adjustable wrench, 12 in.
6 Hex cap bolts, 1/2-20 x 2in.
6 Hex nuts, 1/2in.

5.2 Unpacking and cleanup

1. Finish uncrating saw and inspect for damage.
Should any have occurred, contact your local
distributor. Do not discard any packing material
until saw is set up and running properly.

2. Remove all bolts attaching machine to shipping
pallet. (The wood support beam can be
removed after machine has been connected to
power and the bow raised.)

3. Clean all rust protected surfaces with a cleaner­degreaser or kerosene to remove protective
coating. Do not use gasoline, paint thinner,
mineral spirits, etc. These may damage painted
surfaces.

4. Lubricate all slideways with SAE 10W oil.

5. Compare contents of shipping carton with the
contents list in this manual. Report shortages, if
any, to your distributor.

5.3 Installation

1. The band saw should be located on a solid and
level foundation, preferably concrete. Allow
room for bow swiveling, servicing and for
moving large stock around the machine.

2. Use lifting straps that are isolated from the band
saw’s finished surfaces and knobs, to move
machine to desired location. Position straps
under secure areas; do not strap bow or vise
assembly.

3. Install leveling bolts/nuts/pads, and the leveling
feet as desired, through the base flanges.

4. Place a level on the table surface and check
side-to-side and front-to-back.

6.0 Electrical connections

Electrical connections must be

made by a qualified electrician in compliance
with all relevant codes. This machine must be
properly grounded to help prevent electrical
shock and possible fatal injury.

The MBS-1323EVS-H Horizontal Band Saw is wired
for 3-phase, 230V; the MBS-1323EVS-H-4 is wired
for 3-phase 460V. The machine is not provided with
an electrical plug; you may either attach a proper
UL/CSA-listed plug, or “hardwire” the machine
directly to a service panel.

It is recommended that the band saw be connected
to a dedicated 20 amp circuit with circuit breaker or
time-delay fuse marked “D”. Local codes take

precedence over recommendations.

Before connecting to power source, be sure switch
is in off position.

6.1 GROUNDING INSTRUCTIONS

This tool must be grounded. In the event of a
malfunction or breakdown, grounding provides a
path of least resistance for electric current to reduce
the risk of electric shock. This tool is equipped with
an electric cord having an equipment-grounding
conductor. If a plug is used, it must be plugged into
a matching outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.

Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface
that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or
replacement of the electric cord or plug is
necessary, do not connect the equipment-grounding
conductor to a live terminal.

Check with a qualified

electrician or service personnel if the grounding
instructions are not completely understood, or if
in doubt as to whether the tool is properly
grounded. Failure to comply may cause ser ious
or fatal injury.

8

If hardwired:

Permanently connected tools: This tool should be
connected to a grounded metal permanent wiring
system; or to a system having an equipment­grounding conductor. Make sure a disconnect is
available for the operator. During hard-wiring of the
machine, make sure the fuses have been removed
or the breakers have been tripped in the circuit to
which the drill press will be connected. ALWAYS
FOLLOW PROPER LOCK-OUT/TAG-OUT PRO­CEDURES.

6.2 Extension cords

The use of extension cords is discouraged; try to
position equipment within reach of the power
source. If an extension cord becomes necessary, be
sure it is heavy enough to carry the current your
product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating.

Table 2 shows recommended size to use depending
on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.
