Your tool is equipped with a mode selector
to select one of three speeds or Precision Wrench™ mode. Select
the mode based on the maximum speed/torque needed and
control the speed of the tool using the variable speed trigger
switch

.
Precision Wrench™ (Fig. C)
In addition to low speed impacting modes, this tool features
the Precision Wrench™ 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 3250 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 3250 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.

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.

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
Release variable speed trigger switch to stop operation.
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.
. Press
Material: The type of material and surface finish of the
‑
material will affect fastening torque.
