Blade Guide Adjustment
Overview
The blade guide assembly consists of two roller
guides (bearings) positioned on each side of the
blade to provide blade stabili t y. A third guide (thrust
bearing) is positioned behind the blade to provide
blade support.
There are two blade guide assembli es – an upper
assembly and lower assem bly (see Figure 12).
Adjustments are perform ed in the same m anner f or
each assembly. Each assembly must be adjusted
in turn using the adjustment procedures outlined
below.

Grounding Instructions
r
e
General Information
This Band Saw must be
grounde d while in use to protect the ope r ator
from electri c sho ck.
In the event of a malfunction or breakdown,
grounding provi des a path of least resistance for
electric current to reduce the risk of electric
shock. This tool is equipped with an elec tric cord
having an equipment- groundi ng conduct or and a
grounding plug that looks similar to the plug in
Figure 15. The plug must be inserted into a
matching outlet that is properly installed and
grounded in accordanc e with all local codes and
ordinances.
Do not modify the pl ug pr ovided. If it will not fit
the outlet, have the proper outlet installed by a
qualified elec trician.
Improper connection of the equipmentgrounding 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 equipmentgrounding conduct or. If repair or replacement of
the electric cord or plug is necessary, do not
connect the equipment -groundi ng conductor to a
live terminal.
receptacle as shown (Figure 11), if a properly
grounded outlet i s not available. The tempor ary
adapter should only be used until a properly
grounded outlet can be installed by a qualified
electrician. This adapter is not applicable in
Canada. The green col ored ri gi d ear, l ug, or tab,
extending fr om the adapter, must be connect ed
to a permanent ground such as a properly
grounded outlet box, as shown in Figure 5.
Figure 16
Extens ion Cords
Use only three wire extension cords that have
three-prong grounding plugs and three-pole
receptacles t hat accept the tool’s plug.
Make sure the cord is in good condition and
heavy enough to carry the current your band
saw will draw. An undersized cord will cause a
drop in line voltage, resulting in loss of power
and overheati ng. Table 1 shows the correct size
to use depending on cord l ength and the ampere
rating on your machine’s nameplate. If in doubt ,
use the next heavier gauge. The smaller the
gauge number, the heavier the cord.
Figure 15
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.
Repair or replace a damaged or worn cord
immediately.
115 Volt Operation
As received from the factory, your band saw is
ready to run at 115-volt operation. This band
saw is intended f or use on a circuit that has an
outlet and a plug that looks like the one
illustrated in Figure 4. An adapter with a
grounding ear (Figure 16) may be used
temporarily to connect this plug to a two-pole
Repair or replace a damaged or worn cord
immediately.
