OPERATION CONT.
7. Press the nosepiece with constant force against
the work surface. Do not remove the tool from
work surface until the clutch disengages and the
bit stops rotating, signaling a fully driven screw.
8. Lift the tool enough to relieve all down pres-
sure, allowing the feed mechanism to complete a
full stoke before starting to drive another screw.
The tool must complete a full stoke to advance
screws properly.
9. Fine tune screw depth by first unplugging
screwgun from electrical supply, then adjusting
depth control as shown in Figure 3.
TROUBLESHOOTING
Screws are turning but not driving at all.
1. IMPORTANT! Be sure the screwgun is set to for-
ward and not reverse.
2. Broken or worn out driver bit.
• Call 1-800-706-7337 or your sales rep. for re-
placement parts.
Screws are miss-driving.
What causes mis-drives?
1. Broken or worn out driver bit.
2. Operating the SuperDrive too fast.
3. Not lifting the SuperDrive off the work surface
before driving the next screw.
4. Roller bearing is slipping during the indexing
cycle.
• Pull the strip in reverse, if it slips or comes out,
the index module is worn and must be replaced.
5. Strip is binding in the index module.
• Check for debris that may be built up in the in-
dex module.
6. Burrs on the front face of the tool body prevent-
ing complete cycling of the index module.
• Remove the burrs with a file.
7. Nose piece screw is loose and rubs on the tool
body preventing full cycling of the index module.
• Tighten the nose piece screw securely.
8. Nose piece is bent and rubs on the tool body
preventing full cycling of the index module.
• Straighten it with pliers or replace.
9. Strip is binding in the feed track.
Screws are not seating uniformly.
1. Not enough follow through in driving the
screws.
2. Incorrect setting of the depth control bar. • Re-
adjust.
3. Driver bit is worn and comes out of the recess
before the screw is seated.fully.
• Call 1-800-706-7337 or your sales rep. for re-
placement parts.
4. If 3" screws stick up 3/8" you must call 1-800-
706-7337 for SuperDrive75 replacement. Part#
CWFD16
Screws in the strip are being skipped.
If a screw is skipped and not driven, a tooth may
be broken on the indexing gear.
• The index module must be replaced.
Screw strip slips or comes out effortlessly from in-
dex module.
• Index module is worn and must be replaced.
Bit seems to wear rapidly.
If the depth control bar is set to drive screws too
deeply, excessive torque is required and can cause
excessive wear of the bit. Adjust the screw depth
accordingly.
OTHER POINTS OF ATTENTION
1. If you lose the screw for securing the nose
piece.
• Order item part # CWFB13.
2. If the end plate has been damaged from over
tightening the wing screw, or the wing screw is
broken and the end plate cannot be securely
clamped to the coupler.
• Call 1-800-706-7337 or your sales rep. for re-
placement parts.
MAINTENANCE
1. Read section titled Safety Warnings before
maintaining tool.
2. With tool unplugged from power supply, make
daily inspection checking free movement of nose
and trigger.
• Do not use if parts stick.
3. Occasionally lubricate the index module roller
(as shown in photo as white dots).
• Lubricate with Tri-Flow or WD40.
4. Wipe tool with clean cloth daily and check for
wear.
CHANGING THE INDEX MODULE OR SPRING
1. Remove retainers by loosening the screws and
pushing in the index module about 1/4" so the
retainers can be pushed back and taken out.
2. When replacing the index module make sure
the indexing pin lines up with the entrance groove
on the body.
CHANGING BIT
1. Due to wear or damage, the bit will need to
be changed periodically or when changing from
LOX, Phillips or Square Drive fasteners.

SAFETY WARNINGS
READ AND FOLLOW ALL INSTRUCTIONS
WARNING—When using electric tools, basic
safety precautions should always be followed to
reduce the risk of fire, electric shock and personal
injury, including the following:
1. Keep work area clean and well lit. Cluttered
benches and dark areas invite injury.
2. Avoid dangerous environment. Do not expose
power tool to rain. Do not use power tools in
damp or wet locations. Do not use tool in pres-
ence of flammable liquids, dust or gases. Power
tools can create sparks which might ignite the
dust or fumes.
3. Keep bystanders, children and visitors away
while operating a power tool. Distractions can
cause you to lose control.
4. Guard against electrical shock. Prevent body
contact with grounded surfaces.
5. Double insulated tools are equipped with a po-
larized plug (one blade is wider than the other).
This plug will fit in the outlet only way. If the plug
does not fully fit in the outlet, reverse the plug. If
it still does not fit, contact a qualified electrician to
install a polarized outlet. Do not change the plug
in any way.
6. Do not abuse cord. Never carry tool by cord
or yank it to disconnect from receptacle. Keep
cord away from heat, oil, sharp edges, or moving
parts. Replace damaged cord immediately. Dam-
aged cords increase the risk of electrical shock.
7. When operating tool outside, use an outdoor
extension cord marked with "W-A" or "W". When
using an extension cord, be sure to use one heavy
enough to carry the current your product will
draw.
8. Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention
while operating power tools may result in serious
personal injury.
9. Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep your hair, cloth-
ing, and gloves away from moving parts. Loose
clothes, long hair, or jewelry can be caught in
moving parts.
10. Avoid accidental starting. Be sure switch is off
before plugging in the tool. Carrying tools with
your finger on the switch or plugging in the tool
with the switch on invites accidents.
11. Remove adjusting keys and wrenches before
turning the tool on. A wrench or key that is left at-
tached to a rotating part of the tool may result in
personal injury.
12. Do not overreach. Keep proper footing and
balance at all times.
13. Use safety equipment. Always wear protective
glasses. Dust mask, non-skid safety shoes, hard
hat, or earplugs may be used for appropriate con-
ditions.
14. Secure work. Use clamps or other practical
way to secure and support the work piece to a
stable platform. This leaves both hands free to
operate the tool.
15. Do not force the tool. Use the correct tool
for the application. The correct tool will do the
job better and safer at the rate for which it is de-
signed.
16. Store idle tools. When not in use, tools should
be stored in dry and high or locked place—out
of the reach of children and other untrained per-
sons.
17. Disconnect the plug from power source be-
fore making adjustments, changing accessories,
or storing tool.
18. Maintain tools with care. Keep tool clean. Fol-
low instructions for lubricating and changing ac-
cessories.
19. Check for misalignment or binding of moving
parts, and other conditions that may affect op-
eration. If damaged have the tool serviced by a
Grabber authorized service center before using.
20. Use only accessories recommended by manu-
facturer of tool. Accessories that are suitable for
one tool may become hazardous when used on
another tool.
21. Repairing tool. Any repairs to electric tools
should be performed only by qualified personnel.
Use only authorized parts.
