TOOL USE AND CARE
I
1I.Use clamps or other practical way to sseum and suppoxt the workpiece to a
stable platform. Holding the work by hand or agalnst your body is unstable and may lead to
loss of controt.
17;Do not lome tool. Use the correct W br your application, The correct tool will do
the job better and saferat the rate for which It is designed.
18.Do not use tool H switch does not turn It on or off. Any tool that cannot be controlled
with the swltch is dangerousand must be repaired.
l%Dlsco~nt%ct the plug from the power source before making any adjustments,
changing aceersoriss,or storing the tool. Such preventive safety measures reduce the
r~sk of starting the tool accidentally.
2O.Store idle tmla out of reach of children and other untrained parsons. Toots are
dangerous m the hands of untraned users.
21.Malmln mls with care. Keep cutting tools sharp and clean, Properly maintained
tools with sharp cutting edge are less likely to bind and are easier to control. Do not use a
damaged tool. Tag damaged tools "Do not use' unttl repaired.
2Z.Check for misalignment or bindlng of moving parts, breakage of parts, and any
other condition that may affect the tool's operation. If damaged, have the tool.
serviced before using. Many accidents are caused by porly maintained tools.
23.Use only accessories that are recommended by the manufectunr for your model.
Accessor~esthat may be suttabls for one tool, may become hazardous when used on
another tool.

FUNCnONA L DESCRIPTION
EXTENSION CORDS
Grounded tools require a three wire extension cord. Double insulated tools can use either a
two w thrw wire extension cord. As !he distance from the supply outlet increases, you must
use
a heavier gauge extension cord. Using extension cords with inadequately sized wire muses a
seriws drop in vdtags, resulling in loss of power and possible tool damage. Refer to the tawed
right to determinethe required minimum mre stze.
The smaller the gauge number of the wire, the greater the capacity of the cord. For mpk, a 14
gauge cord can carry a higher current than a 16 gauge cord. Won using more than one exremion
nrrd to make up the totat length, be sure each cord oonta~ns at least the mini~llum wire size
required. If you am using one exlension cord for more than one tooh add #e namqlate
amperes and use the sum to determine the requimd minimum wm srze.
Quwm br orsing Exh$lon Cords
If yw are using an exlension cord wtdwrs, be sure it is marked with the sufmc 'W-A'
(W in Canada) to indicate that it is acceptable for outdoor use.
Ba sure pr extension cord is properly wired and ingood elactrieal mdltlon. Alweys

Udng Wire Wheel Brushgs (Flg. 7)
Wire wheel brushes are useful for remllag rust, scale, burrs, weld slag, etc. A wtde
variety of wire brushes are available for maw applications.

Test wire wheel brush for balance and loose or damaged wires by running tocl at no
load spd for at least one minute kfore applying it to your work. During this time, no
one should stand in front of or inline with it. When applying brush to work, awld using
too much pressure. This causes met-bending of wires and heat build-up resulting in
premature
wite breakage, rapid dulling and reduced brush life, Instead of using more
pressure, try a wire wheel brush with more aggressive cutting act~on (increased wire
size, decreased wire length or different brush type. E.e. knot type instead of crimped
wire type).
