Cleaning
WARNING:
Blow dirt and dust out of the main housing
with dry air as often as dirt is seen collecting in and around
the air vents. Wear approved eye protection and approved
dust mask when performing this procedure.
WARNING:
Never use solvents or other harsh chemicals
for cleaning the non‑metallic parts of the tool. These
chemicals may weaken the materials used in these parts.

Lubrication
Your power tool requires no additional lubrication.
MAINTENANCE
Your power tool has been designed to operate over a long
period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and
regular cleaning.
WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories.
An accidental
start‑up can cause injury.
The charger and battery pack are not serviceable.
Your impact tool generates the following maximum torque.
nOTE:
Output fastening torque is dependent on the speed
selected, with the highest provided in the Impact Assist™ mode.

Always check torque with a torque wrench, as the fastening
torque is affected by many factors including the following:
‑
Voltage:
Low voltage, due to a nearly discharged
battery, will reduce fastening torque.
‑
Accessory size:
Failure to use the correct accessory size
will cause a reduction in fastening torque.
‑
Bolt size:
Larger bolt diameters generally require
higher fastening torque. Fastening torque will also vary
according to length, grade, and torque coefficient.
‑
Bolt:
Ensure that all threads are free of rust and other
debris to allow proper fastening torque.
‑
Material:
The type of material and surface finish of the
material will affect fastening torque.
‑
Fastening time:
Longer fasten ing time results in
increased fastening torque. Using a longer fastening
time than recommended could cause the fasteners to
be overstressed, stripped or damaged.
Usage (Fig. A)
CAUTION:
Ensure fastener and/or system will withstand
the level of torque generated by the tool. Excessive torque
may cause breakage and possible personal injury.
1. Place the accessory on the fastener head. Keep the tool
pointed straight at the fastener.
2. Press variable speed trigger switch
1
to start operation.
Release variable speed trigger switch to stop operation.
Proper hand position requires one hand on the main handle
9
and one hand on the battery pack. Hold tool firmly with both
hands to control the twisting action of the tool.
OPERATION
Instructions for Use
WARNING:
Always observe the safety instructions and
applicable regulations.
WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories.
An accidental
start‑up can cause injury.
Anvil (Fig. A, D)
WARNING:
Use only impact accessories. Non‑impact
accessories may break and cause a hazardous condition.
Inspect accessories prior to use to ensure that it con tains
no cracks.
CAUTION:
Inspect anvils and hog rings prior to use.
Missing or damaged items should be replaced before use.
Place the switch in the locked off (centre) position or remove
battery pack before changing accessories.
To install an accessory on the hog ring anvil,
firmly push
accessory onto the anvil

. The hog ring

compresses to allow
the accessory to slide on. After accessory is installed, the hog
ring applies pressure to help provide accessory retention.
To remove an accessory,
grasp the accessory and firmly pull
it off.
Impact Assist™ (Fig. E)
In addition to normal impacting modes, this tool features the
Impact Assist™ mode which grants the user greater control in
both fastening and loosening applications. When set in forward,
the tool will fasten at 2000 RPM until impact begins. The tool
will then pause for 0.5 seconds before continuing to impact at
a rate of 3100 IPM, providing the user with greater control and
reducing the chance of overtightening or damaging material.
When set in reverse, the tool will impact at a normal speed and
rate of 3100 IPM. Upon sensing that the fastener has broken
free, the tool will cease to impact and will reduce speed to help
prevent “run‑off” of loose hardware.
