4. INTRODUCTION
4.1 SCOPE
This hand-held cordless impact wrench is intended to tighten and loosen mechanical fixings (nuts,
bolts, etc). It is intended for domestic and light commercial use only. Any other application is
considered misuse.
There is no mechanism for adjusting or regulating the output torque. All fixings should be finished
using a torque wrench.
Power product 89518 is supplied “naked” without battery pack or charger. Draper 20V Power
Interchange tools all use universal 2.0 and 4.0Ah batteries and chargers, enabling each battery pack
to fit all tools within the range (see the table on page 11 for the batteries and chargers available).

9.7 OPERATION
Proper fastening torque is determined by the kind of fastening, the size of the fastening or the
material or workpiece.
– It is advisable to perform a test operation to determine the proper fastening time for the
fastening you are using.
– Hold the wrench in straight alignment to the fastening.
– Depress the wrench and use for the required amount of time.
– After fastening, always check the torque with an appropriate torque wrench.
Note:
Do not use this tool to install wheel nuts on wheels without a torque limiting device. Doing
so could result in galled or broken nuts.
Note:
Using a universal joint or extension bar may reduce the fastening force of the impact
wrench and require longer fastening time.
Note:
Using an impact wrench creates heat. The metal housing at the front of the wrench will
become hot. In certain circumstances, the force required to tighten or remove fixings may cause
the fixings themselves to become very hot! Wear suitable gloves to prevent burns.
