Auto-feed operation
Setup
1. Ensure the screw is in line with the Screw Centre Indicator (1)
2. Set the depth adjustment to the mid-point
3. Set the Speed Limiter Control (16) to the minimum setting for first use
4. Ensure the Forward/Reverse Selector (14) is in the forward position to insert screws into the
workpiece as indicated on the tool body
Operating
1. Place the Stopper Base (21) over the location for the first screw 90° to the surface
2. Use the Screw Centre Indicator (1) to aid positioning
3. Hold the drill by the Insulated Hand Grip (18) and the recess between the Auto-Feed Mechanism
(8) and screwdriver gearbox cowling
GB
DO NOT: Hold the tool close to any exposed mechanical area or the screws of the Auto-Feed
Mechanism.
DO NOT: Hold the tool by the screwdriver gearbox cowling if there is a risk of contacting electrical
cables in use.
4. Squeeze the Trigger (15) to operate. You can either squeeze the Trigger before each plunge or
use the Lock On Button (17) to lock the drill 'on'
5. Carefully push the Stopper Base against the material so the Auto-Feed Mechanism is compressed
and the screwdriver connects with the screw. As this happens, the inner part of the Auto-Feed
Mechanism submerges into the outer case of the Auto-Feed Mechanism and the drive is enabled
on the Screwdriver Power Tool (11)
6. Once the screw is inserted to its maximum level, carefully remove the Stopper Base from the work
surface so the Auto-Feed Mechanism is fully extended again
7. After you have inserted the first screw, adjust the required screw depth as described in 'Screw
Depth Adjustment' if necessary
8. The Auto-Feed Mechanism has brought the next screw up to the mounting point and operating
can be repeated immediately
Notes
• Always ensure that material is secure. If appropriate use a vice or clamp to hold the work
• The technique of connecting to and driving screws can be improved by operating the drill at
a lower speed while connecting to the screw by using light pressure on the Trigger and then
increasing Trigger pressure when driving the screws into the material. This will reduce wear on
the Collated Screwdriver Bit (25)
• Practising with scrap material is recommended in order to familiarise yourself with the tool
CAUTION: The Auto-Feed Mechanism is not designed for hard material. It relies on easy entry for
the screw into the material. It is designed for drywall/plasterboard, low density wood and other similar
materials. While it may work with some harder materials, especially when used vertically, it can also
be problematic in use for such materials. It cannot be used to secure plasterboard/drywall to masonry
or metal.
This is not a fault with the tool.
CAUTION: Applying excess pressure does not result in faster or more efficient screwdriving. If the
pressure applied to the auto-feed screwdriver has a noticeable effect on the speed of the auto-feed
screwdriver, then reduce the pressure. Overloading the auto-feed screwdriver will reduce its service
life.
Depth Stop Operation
The tool can be used for individual insertion and removal of screws. The Depth Stop Collar (22)
ensures the screw heads are at the correct level for plasterboard/drywall but the same head level is
also useful for many other applications.
1. Ensure the correct 25mm length screwdriver bit is fitted to the Bit Holder Extension (23), (PH2
typically for plasterboard/drywall) and the Depth Stop Collar is also fitted to the tool
2. Make sure the Forward/Reverse Selector (14) is correctly set for insertion or removal
3. For most applications, set the Speed Limiter Control (16) to the minimum setting
4. Insert the screwdriver bit tip into the head of the screw to engage
5. Apply light pressure to the Trigger (15) and the screw head to engage the drive of the tool
Note: Use a faster speed setting once you are more familiar with the tool
Note: For use as a standard powered screwdriver without the Depth Stop reducing access to screws,
replace the Bit Holder Extension with a longer length bit holder or use ¼" screwdriver bits longer than
25mm.

Accessories
• A range of accessories and consumables, including GMC GMCAFSB33 (33mm 50pk) and
GMCAFSB42 (42mm 50pk) collated screw belts, is available from your GMC stockist. Spare parts
can be obtained from toolsparesonline.com
Maintenance
WARNING: ALWAYS disconnect from the power supply before carrying out any inspection,
maintenance or cleaning.
General inspection
• Regularly check that all the fixing screws are tight
• Inspect the supply cord of the tool, prior to each use, for damage or wear. Repairs should be
carried out by an authorised GMC service centre. This advice also applies to extension cords
used with this tool
Cleaning
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly, and
shorten the machine's service life. Clean the body of your machine with a soft brush, or dry cloth.
If available, use clean, dry, compressed air to blow through the ventilation holes
• Clean the tool casing with a soft damp cloth using a mild detergent. Do not use alcohol, petrol or
strong cleaning agents
• Never use caustic agents to clean plastic parts
Cleaning and lubricating the mechanism
The Auto-Feed Mechanism (8) may require occasional cleaning and the Metal Guides (7) require
lubrication to maintain reliable operation.
1. Remove any fitted Screw Belt (20)
2. Press down the Screw Length Adjustment Button (4) and pull the Stopper Base (21) carefully from
the Auto-Feed Mechanism (8) housing and remove
3. Allow the main mechanism to drop slightly
4. Clean with compressed air or a small brush especially the channel the Collated Screwdriver Bit
(25) fits into
5. Apply light grease to the Metal Guides (7)
6. Check parts are in good working condition
7. Re-position the Auto-Feed Mechanism in-line with the Metal Guides and refit the Stopper Base
8. Do a quick check to make sure the Auto-Feed Mechanism is plunging normally. If not dis-
assemble and re-assemble
Brushes
• Over time the carbon brushes inside the motor may become worn
• Excessively worn brushes may cause loss of power, intermittent failure, or visible sparking
1. To replace brushes, remove the four screws that secure the side of the handle indicated in Image
B and remove the plastic panel
2. Remove the two carbon brushes held by the brush retainers indicated in Image C and fit new
brushes
3. Refit plastic panel
4. Check tool is running normally. The carbon brushes may take a small amount of time to bed in
and work optimally
Storage
• Store this tool carefully in a secure, dry place out of the reach of children
Disposal
Always adhere to national regulations when disposing of power tools that are no longer functional and
are not viable for repair.
• Do not dispose of power tools, or other waste electrical and electronic equipment (WEEE), with
household waste
• Contact your local waste disposal authority for information on the correct way to dispose of
power tools
