2. GUARD AGAINST ELECTRICAL SHOCK by
preventing body contact with grounded surfaces,
For example; Pipes, radiators, ranges, refrigerator
enclosures.
3. KEEP GUARDS IN PLACE and in working order.
4. KEEP WORK AREA CLEAN.Cluttered ames and
benches invite accidents.
5. AVOID DANG EROUE ENVlRONM ENT.Don't use
power tool in damp or wet locations or expose to
rain. Keep work area well tit.
6. KEEP CHILDREN AND VISITORS AWAY. All
visitors should wear safely glasses and be kept a
safe distance from work area. Do not let visitors

7. STORE IDLE TOOLS. When not in use tools
should be stored in e dry and high or locked-up
place - out of the reach of children.
8. DON'T FORCE TOOL. It will do the job bettar and
safer at the rate for which it was designed,
9. USE RIGHT TOOL. Don't force small tool or
attachment fo do the job of a heavy duty tool. Don't
use tool for purpose not intended - for example -A
circular saw should never be used for cutting tree
limbs or logs.
10. WEAR PROPER APPAREL. Do not wear loose
clothing or jewelry that can get caught in fool's
moving parts and cause personal injury. Rubber
gloves and non-skid footwear are recommended

The following guidelines may be used In determln-
in_gcorrect speed for various applications:
L(_W speed is ideal when minimum speed and power
is required. For example: starting holes without
center punching, mixing paint, and drilti_g in
ceramics.
MEDIUM speed is suitable for drilling hard metals,
plastics, and laminates,
HIGH speed produces best results when maximum
bower is requLred. For example: drilling in wood; soft
metals such as aluminum, brass, and copper, and
when using ddvlng accessories.

POWER CORD
See Figure 6.
An added feature of your new e_ectronic drill is an
extra-long 10' power cord that stays soft and flexible
in cord weather, The plug design is shaped 8o that it
won't snag on your work during use. A molded cord
clip on the plug makes cord storage easier.
DRILLING
See Figure 7,
1. Depress and release the switch trigger to be sure
your drill is in the "Off" position before connec-
ting it to power supply.
2. Check the direction of rotation lever for correct
setting (forward or reverse).
3, Secure the material to be drilled in a vise or with
clamps to keep tt from turning as the drill bit
rotates,
4. Plug your drill into power supply source.
5. Hold your drill firmly and place the bit at the
point to be drilled.
6. Depress the switch trigger to start your drill. DO
not lock the switch "On" for Jobs where the drill
may need to be stopped suddenly.
7. Move the ddll bit into the workplece applying on-
ly enough pressure to keep the bit cutting. Do
not force your drill or apply side pressure to
slon ate ahole. Let your drill and bit do the work.
See _=lgure 7.
When drilling hard smooth surfaces use a center
punch to mark the desired hole location. This will
prevent the drill bit from slipping oft center as the
hole is started, However, the variable speed feature
allows starting holes without center punching it
desired. TO accomplish this, simply operate your
drill at a low speed until the hole is started.
When drilling metals use a light oll on the drill bit to
keep it from overheating. The oil will prolong the life
of the bit and tncrease the drilling action,
If the bit jams in the workplace or if your drill stalls,
stop the tool Immediately. Remove the bit from the
workpiece and determine the reason for Jamming.
Avoid running your drill at low speeds for extended
periods of time. At lower speeds under constant
usage, your drill may become overheated, It this oc-
curs, operate drill without a load and at full speed to
cool it more quickly.

When electric tools are used on fiberglass boats,
sports cars, etc, it has been found that they are sub-
ject to accelerated wear and possible premature
failure, as the fiberglass chips and grindings are
highly abrasive to bearings, brushes, commutator,
etc. Consequently it is not recommended that this
tool be used for extended work on any fiberglass
material. Curing any use on fiberglass it is extremely
im_ortant that the tool is cleaned frequently by blow-
ing with an air et. ALWAYS WEAR SAFETY GOG.
