health surveillance.
We recommend a programme of health surveillance to detect early symptoms of vibration injury so that management procedures can
be modified accordingly.
Personal protective equipment.
We are not aware of any personal protective equipment (PPe) that provides protection against vibration injury that may result from
the uncontrolled use of this tool. We recommend a sufficient supply of clothing (including gloves) to enable the operator to remain
warm and dry and maintain good blood circulation in fingers etc. Please note that the most effective protection is prevention, please
refer to the correct use and maintenance section in these instructions. Guidance relating to the management of hand arm vibration
can be found on the Hsc website www.hse.gov.uk - Hand-Arm Vibration at Work.

4. prepArAtiOn
4.1.
recommended hook-up is shown in fig.1.
wArninG!
ensure that the air supply is clean and does not exceed 90 psi while operating this tool. too much air pressure and/or
unclean air will cause excessive wear and may be dangerous, causing damage and/or personal injury.
4.2.
ensure that the tool trigger is not depressed before connecting to the air supply.
4.3.
You will require an air pressure of 90psi, and an air flow of 5cfm per tool.
4.4.
drain the air tank daily. Water in the air line will damage the tools and invalidate your warranty.
4.5.
clean the compressor air inlet filter weekly.
4.6.
line pressure should be increased to compensate for unusually long air hoses (over 8 metres). the minimum hose bore should be
1/4” and fittings must have the same inside dimensions.
4.7.
Keep hoses away from heat, oil and sharp edges. check hoses for wear and make certain that all connections are secure.
4.8.
couplings - vibration may cause failure of a quick change coupling that is connected directly to the air tools.
4.8.1.
to overcome this, connect a leader hose (sealey model number AH2r) to the tools.
4.8.2.
A quick change coupling may then be used to connect the leader hose to the air line recoil hose. see figs.1 & 2.
5. OperAtiOn
the air ratchet wrench has a hardened steel anvil with trigger operated power control, it is suitable for use in the engine bay where
there is limited space for hand operated ratchets.
wArninG!
ensure that you read, understand and apply the safety instructions in section 1 before use. Additionally the
following safety instructions are specific to this tool.

dO nOt
use any additional force upon the wrench in order to remove or tighten a nut.
5.1.
Only use sockets specifically designed for use with a ratchet wrench.
5.2.
connect the wrench to the air supply as in section 4.
5.3.
Place the socket over the subject nut and depress the trigger to operate the wrench.
5.4.
to change ratchet direction turn the switch on the tool head. f = forward r = reverse.
