Intended Use

Mains-powered portable power tool for driving collated screws into plasterboard/drywall and light,
low density wood with automatic reloading of screws when used with the auto-feed attachment. Also
operates as a powered plasterboard/drywall screwdriver with depth stop when used with the Depth

Unpacking Your Tool

• Carefully unpack and inspect your new sander. Familiarise yourself with all its features and
functions
• Ensure that all parts of the tool are present and in good condition. If any parts are missing or
damaged, have such parts replaced before attempting to use this tool

Before Use

WARNING: Ensure the tool is disconnected from the power supply before attaching or changing any
accessories, or making any adjustments.
Assembling for auto-feed use
1. Push the Collated Screwdriver Bit (25) firmly into the Bit Holder of the tool (Image A). It is held in
place by captive ball-bearing mechanism and there will be some resistance
2. Carefully fit the Auto-Feed Mechanism (8) over the Collated Screwdriver Bit. The Auto-Feed
Mechanism can be fitted at multiple angles, depending on use, although the normal position
is the Lower Screw Belt Channel (19) directly in line with the power tool handle. Three captive
ball-bearings secure the Auto-Feed Mechanism to the power tool. It simply clicks into place and
is removed by simply pulling the Auto-Feed Mechanism from the tool. No additional tools are
required

3. To set the Auto-Feed Mechanism to the length of the screws, press and hold in the Screw Length
Adjustment Button (4) and either push in or pull out to the required length by holding and moving
the Stopper Base (21). The screw length is indicated by the Screw Length Scale (5) and can be
adjusted from 25 – 55mm in 5mm click increments

Screw Belt Channel (3).
Assembling for Depth Stop Use
1. Pull off the Auto-Feed Mechanism (8) if fitted
2. Remove the Collated Screwdriver Bit (25) if fitted. The Collar Holes (24) of the Depth Stop Collar
(22) can be used to grip the Collated Screwdriver Bit if it is difficult to pull free from the Bit Holder
of the tool (Image A)
3. Insert the Bit Holder Extension (23) into the bit holder of the tool
4. Fit a PH2 ¼" screwdriver bit to the Bit Holder Extension
5. Fit the Depth Stop Collar to the tool by simply pushing over the bit holder of the power tool

Operation
WARNING: ALWAYS wear eye protection, adequate respiratory and hearing protection, as well as
suitable gloves, when working with this tool.
Main Unit
Forward/Reverse
Direction can be changed using the Forward/Reverse Selector (14).
• Do not attempt to move the Forward/Reverse Selector whilst the drill is operating
• Ensure the Forward/Reverse Selector is fully to the left or right so either forward or reverse is
cleanly selected
Speed control
• The maximum rotation speed of the tool can be varied using the Speed Limiter Control (16).
This governs the maximum speed of the Trigger (15)
• The Speed Limiter Control indicates '+' or '-' rotation to increase or decrease speed
Trigger
• To start the tool, squeeze the Trigger (15). The further the Trigger is squeezed the faster
the speed
• To stop the tool, release the Trigger
Lock on button
• The auto-feed screwdriver is equipped with a Lock-On Button (17). This allows the Trigger (15) to
be locked into the "on" position for tasks that require extended continuous running
• To use the lock on function, depress the Lock-On Button whilst squeezing the Trigger, the Trigger
can then be released and the drill will continue to operate
• To stop the auto-feed screwdriver, squeeze, then release the Trigger
Pressure Clutch
• The tool is fitted with an internal pressure clutch that only engages when the drive is pushed
against the screw head, either when the Auto-Feed Mechanism (8) is used and plunged, or with
individual screws.
IMPORTANT: As only light additional pressure operates the drive, be careful in use not to be taken by
surprise when the drive engages.
Auto-feed Mechanism
Screw Length Adjustment
• To adjust for different screw sizes, press down the Screw Length Adjustment Button (4) and adjust
the length position by pulling or pushing the Stopper Base (21).
