Intended Use

Battery-operated general-purpose impact wrench, suitable for light to medium duties,
driving nuts and bolts, using suitable square drive sockets.

Unpacking Your Tool

• Carefully unpack and inspect your new impact wrench. 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

IMPORTANT:

Your impact wrench’s battery comes partly charged. It is recommended that

you fully charge the battery before using the tool for the first time. It is also recommended
that you fully drain then fully charge the battery for a further 2 times to condition the
battery, ensuring optimal usage is achieved for the duration of the battery life.

Charging the Battery

WARNING:

ONLY use the supplied Battery Charger (11) to charge the supplied

Battery (9) or additional purchased batteries that are specifically designed for this tool.

WARNING:

The Battery Charger is designed for indoor use only and MUST NOT be

used in damp or wet conditions.

WARNING:

Failure to follow the correct procedure when charging batteries will result

in permanent damage.

Note:

Fully charging the Battery can take 3–5hrs, depending on how depleted the battery

charge is when inserting the Battery into the Battery Charger (11). Also, it may take longer
if the Battery has been in a discharged state for an extended period of time.
1.  Plug the Mains Plug (12) into a mains socket
2.  Insert the Battery (9) into the Battery Charger (11) (it can only fit one way) and turn the
  mains power on at the socket
3.  The Red LED (14) will illuminate, which indicates charging
4.  The Green LED (13) will illuminate once the battery is fully charged

Notes about battery charging

•  The LED Battery-Charge Indicator (4) will display the battery’s charge level: Green =
  charged; Amber = mid-charged; and Red = low charge/battery needs charging
•  The battery should be charged at ambient temperatures between 10 and 40°C (ideally
  around 20°C)
•  After charging, allow 15 minutes for the battery to cool before use
•  Ensure that the charger is disconnected from the mains supply after use, and is
  stored correctly
•  DO NOT leave batteries on charge for extended periods and NEVER store batteries
  on charge
•  The Battery Charger monitors battery temperature and voltage while charging. Remove
  the Battery once charging has been completed to maximise charge cycles of the battery
  and not waste power

•  Batteries can become faulty over time, individual cells in the battery can fail and the
  battery could short. The charger will not charge faulty batteries. Use another battery,
  if possible, to check correct functionality of the charger and purchase a replacement
  battery if a faulty battery is indicated
•  DO NOT store Lithium-Ion (Li-Ion) battery packs in a discharged state long term. This
  can damage the Lithium-Ion cells. For long-term storage, store batteries in a high
  charge state, disconnected from the power tool
•  The capacity of batteries will reduce over time. After 100 charge cycles, the battery’s
  operation time and the maximum torque performance of the impact wrench will slightly
  reduce. This decline will continue until the battery has minimal capacity after 500
  charge cycles. This is normal and not a fault with the battery pack

Fitting the Battery

1.  Ensure the Battery (9) has adequate charge (see ‘Charging the battery’)
2.  Insert the Battery into the Hand Grip (7) (the Battery can only fit one way) until the
  Battery Release (8) clips lock into place with a faint clicking sound
3.  Your impact wrench is ready to use

Removing the Battery

1.  Press in and hold the Battery Release (8) clips on both sides of the Hand Grip (7) then
  pull out the Battery (9)
2.  The Battery can now be inserted into the Battery Charger (11) to charge, if required (see
  ‘Charging the Battery’), or stored in a cool, dry place

Fitting and Removing Sockets

1.  Push a suitable socket on to the Square Drive (2). The Retaining Ball (1) will keep the
  socket in place
2.  To remove, pull the socket off the Square Drive

Note:

Make sure any sockets used are hardened and suitable for use with an impact

wrench.

Operation

Direction control

WARNING:

The rotational direction of the Square Drive (2) or socket cannot be

changed while the impact wrench is running. DO NOT attempt to change the rotational
direction while the impact wrench is running; this may cause permanent damage to the
tool.
•  Use the Forward/Reverse Switch (5) to change the direction of the Square Drive or
  socket rotation
•  For anti-clockwise rotation, push the switch to the right
•  For clockwise rotation, push the switch to the left

Note:

When the Forward/Reverse Switch is in the central position, the impact wrench

is locked and cannot be switched on. Use this setting as a safety feature to prevent the
impact wrench from being switched on accidentally.

Switching On/Off

WARNING:

ALWAYS wear adequate personal protective equipment when setting up

and operating this machine.
1. To start the impact wrench, squeeze the Trigger Switch (6)
2. The built-in LED Work Light (10) will illuminate when the Trigger Switch is squeezed

Note:

If the Trigger Switch cannot be pressed down, check that the Forward/Reverse

Switch (5) is not set to its middle position, which locks the device (see ‘Direction control’)
3.  The speed of the impact wrench is controlled by the movement of the trigger: the more
  the Trigger Switch is pressed down, the faster the impact wrench will run
4.  Release the Trigger Switch to stop the machine

WARNING:

If the power tool gets excessively hot in use, stop using the tool

immediately and allow to cool before continuing work. The cooling period can be reduced
by operating the impact wrench at maximum speed with no load. Always make sure the
Motor Vents (3) are not blocked and do not allow dust to enter the body of the tool through
the Motor Vents; dust, especially metallic dust, may damage or destroy the tool.

Accessories

• A full range of accessories including various types of sockets is available from your
Silverline stockist. Spare parts can be obtained from

Maintenance

WARNING:

Before carrying out any maintenance/cleaning of the Battery Charger

(11), ALWAYS disconnect from the mains power supply. Remove the Battery (9) before
carrying out any maintenance/cleaning of the impact wrench.

Note

: Both the impact wrench and the Battery Charger contain no user-serviceable parts. If

the device does not perform as outlined in this manual, return it to an authorised Silverline
service centre for repair.
