GENERAL SAFETY
All personnel in the vicinity of the equipment should wear as a minimum the following personal
protective equipment (PPE):-
Safety Glasses.
Hearing Protection.
Full Length Sleeves / Trousers.
Steel Toe Cap Shoes or Steel Toe Cap Boots.
Safety Gloves
The end user of this equipment should carry out their own risk assessments prior to operating.
Only use VC-RAD Select wrenches with impact quality sockets. Do not use with extension bars or
universal joints.
Do not use in the presence of explosive gases or liquids - fire/explosion hazard
Prevent unintentional starting. Ensure the switch is in the off position before connecting to a power source
and/or battery pack, picking up, or carrying the tool. Carrying power tools with your finger on the switch
or energizing power tools that have the switch on invites accidents.
Only use VC-RAD Select wrench with 240v or 110v electrical power supply (dependant on model
purchased)
To prevent entanglement with rotating parts operators must not wear loose clothing, ties, jewellery etc…
Long hair must be tied back.
Always keep hands, fingers and body parts clear of the reaction arm at all times. Trapping in this area can
result in serious personal injury.
All Electrical equipment and ancillary products should be inspected for damage and irregularities prior to
use. If in doubt do not use.
Avoid body contact with earthed (grounded) surfaces. There is an increased risk of electric shock if your
body is earthed (grounded).
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of
electric shock.
If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit Interrupter
(GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
CAUTION: ANY MODIFICATION TO THE EQUIPMENT OR CHANGE OF USE BY
ANYONE OTHER THAN W. CHRISTIE WILL INVALIDATE W. CHRISTIE
