If the fastener is protruding, increase the air pressure in increments of 0.5 bar, checking the result
after each new adjustment;
If the fastener is driven into an excessive depth reduce the air pressure I increments of 0.5 bar until
the result is satisfactory.
You should endeavor in any event to work with the lowest possible air pressure. This will give you
three significant advantages;
1.energy will be saved,
2.less noise will be produced,
3.a reduction in fastener driving tool wear will be achieved.
Avoid triggering the fastener driving tool if the magazine is empty.
Any defective or improperly functioning fastener driving tool must immediately be disconnected
from the compressed air supply and passed to a specialist for inspection.
In the event of longer breaks in work or at the end of the working shift, disconnect the tool from the
compressed air supply and it is recommended to empty the magazine.
The compressed air connectors of the fastener driving tool and the hoses should be protected
against contamination, the ingress of coarse dust chips, sand etc, will result in leaks and damage to
the fastener driving tool and the couplings.
V. Maintenance
Disconnect the tool from the compressor before adjusting, clearing jams, servicing &maintenance,
relocating and during non operation.
Regular lubrication, if your tool without using the in-liner automatic oilier, place 2 or 6 drops of
pneumatic tool oil into the air inlet before each work day or after 2 hours of continuous use
depending in the characteristic of workpiece or type of fasteners.
Air-operated tools must be inspected periodically, and worn or broken parts must be replaced to
keep the tool operating safely and efficiently. Check and change all worn or damaged O-ring, Seals,
etc. Tight all the screws and caps in case personal injury.
Make regular inspection for free movement of trigger, Spring and safety mechanism to assure safe
system is complete and functional: no loose and missing parts, no building or stocking parts.
Keep magazine and nose of tool clean and free of any dirt lint or abrasive particles.
When temperatures are below freezing, tools should be kept warm by any convenient, safe
method.
