RISK OF HAND-ARM VIBRATION INJURY
air supply
STARTING WORK
These tools may cause Hand-arm Vibration Syndrome injury
if their use is not adequately managed. We advise you to
carry out a risk assessment and to implement measures
such as; limiting exposure time [i.e. actual trigger time, not
total time at work], job rotation, ensuring the tools are used
correctly, ensuring the tools are maintained according to
our recommendations, and ensuring that the operators wear
personal protective equipment [PPE] particularly gloves and
clothing to keep them warm and dry. Employers should
consider setting up a programme of health surveillance to
establish a benchmark for each operator and to detect early
symptoms of vibration injury.
We are not aware of any PPE that provides protection
against vibration injury by attenuating vibration emissions
.
See ‘Technical Specifications’ section for vibration emission
data.
Further advice is available from our Technical Department.
We strongly advise you to visit the Health & Safety
Executive website http://www.hse.gov.uk/vibration This site
provides excellent advice and information on HAV and it
includes a Hand-arm Vibration Exposure Calculator that is
easy to use to work out the daily vibration exposure for
each of your operators.
The compressed air must be free from water or contamination.
Always clear the air hose before connection to the tool.
Ensure that no moisture (condensation) is present.
Ensure that a minimum 19mm (3/4”) anti-static bore airline is
used and that all couplings are tight and secure. If possible
try to limit the length of airline to 33 ft. (10 metres) (Air
consumption is shown under Technical Specifications at the
end of these instructions).
Where extra length airline is necessary, each additional 50 ft.
(15 metres) of airline used, will drop the pressure at the tool by
approximately 3psi.
Correct operating pressure for this tool is 6.2 bar (90psi)
Do not let the operating pressure fall below 5.5bar (80p.s.i.)
or rise above 6.9bar (100 psi) absolute maximum.
The compressor must be able to supply a minimum of 47 lps
(100cfm) In particularly cold weather it is recommended that a
proprietary anti-freeze lubricating oil is used.
Prior to operating the tool check that all fittings are secure,
free from leaks and that air hoses are in good condition.
That all parts of the tool are fully screwed together and
secure, if in any doubt ask your supervisor before using
this equipment.
That a liberal amount of lubricant has been put into the air inlet
of the tool. (See recommended lubricants) Safe use of this tool
requires a solid stance and secure foothold; the operator must
adopt a firm and stable position at all times.
Recommended Lubriants
Oil the tool before use. Put a few drops of one of the following
zinc free air tool lubricants through the air inlet.
SHELL
S22 or R10
CATROL
Hyspin ZZ32
Always use clean oil from a sealed container and ensure
ignition temperature is above 185degC°.
Remove the lifting pin from the bottom of the handle to
release the handle, refit in to the block-lifting bracket to
prevent its loss. Never run the tool with the handle fastened
to the main body. The most efficient scaling action is to move
the tool back and forth until the desired finish has been
achieved. Never run the tool continuously in the same place
as this will severely mark the surface and may cause cutter
head damage.
To operate the tool simply turn the ball valve so that he
lever is in line with the handle. If the tool is new, optimum
performance will be achieved after 15mins “running in”
of the brush seals (29). Complete a small area noting the
performance; stop the machine, inspect the finish produced.
To switch off, simply return the ball valve lever to 90° to the
handle whilst continuing to move the tool back and forth.
Handled correctly the SF11Ex Deck Hammer will work quickly
and efficiently. Gloves and personal protective equipment
must be worn when using this tool. The tool will ride
irregularities of up to 5mm (1/4”). Anything greater will risk
cutterhead damage. Care must be taken to avoid damaging or
tripping over the air hose. Once the task is completed, return
handle to the upright position and insert the handle-locking
pin (11) for transportation.
VERY IMPORTANT
Only Trelawny Beryllium Copper Heads must be used in
this tool. DO NOT substitute with any other head.
