• Never point the product at anyone.
• Never start the product when it is lying on the ground.
• Take care when setting the product down to prevent
accidental operation.
• Compressed air is dangerous. Never point an air hose at
yourself or co-workers. Never blow clothes free of dust with
compressed air.
• Never disconnect a pressurized air hose. Always turn off the
air supply and bleed the product before disconnecting a hose.
• Keep hands, loose clothing and long hair away from
impacting end of product.
• Anticipate and be alert for sudden changes in motion during
start up and operation of product.
• Keep body stance balanced and firm. Do not overreach when
operating this product. High reaction torques can occur at or
below the recommended air pressure.
• Product may continue to impact briefly after the throttle is
released.
• Product can vibrate in use. Vibration, repetitive motions or
uncomfortable positions may be harmful to your hands and
arms. Stop using product if discomfort, tingling feeling or pain
occurs. Seek medical advice before resuming use.
• Never operate product unless it is assembled properly and the
product is held firmly against the wing nut.
• This product is not designed for working in explosive
atmospheres.
• This product is not insulated against electric shock.
• Excessive hammering on nut can damage both product and
hammer unions.
• Personnel should never hammer on unions or treating pipe
when pressure is present.
• Always keep personnel away from flow lines while under
pressure.
• Assembly of unions with Safety Hammer should be done by
persons qualified to do so either by training or reading and
understanding the manual. Training is available on a regular
basis from Weir SPM. Contact Weir SPM at 1-800-342-7458 for
more information.
• Product should not be assembled by anyone other than
personnel specifically trained in Weir SPM Procedures.
• The use of pressurized components in oilfield operations is
inherently dangerous. Personnel working around energized
equipment and flow lines should use extreme care and observe
all applicable safety precautions. Proper use of this equipment
can reduce but not eliminate the risk of severe personal injury
or death.
Weir SPM has determined that the Safety Hammer,
when used in accordance with these recommended
practices, will produce adequate make-up and break-
out power.
It is important to note that operating conditions will
differ among service companies and their procedures.
Type and technique of operations vary drastically
around the world. Customers must evaluate their
specific application and establish procedures and
proper maintenance to guarantee that connections are
properly assembled. Weir SPM is available to provide
guidance, but the end-user of the equipment has
ultimate say and responsibility on how it is applied.
GENERAL INFORMATION
It is critical that, since most Weir SPM products
generate, control or direct pressurized fluids, those
who work with these products be thoroughly trained
in their proper application and safe handling. It is also
critical that these products be used and maintained
properly.

WARNING
OVERVIEW
The Safety Hammer is designed as an alternative to the sledge
hammer when working with hammer union products used
within the oil and gas industry. The Safety Hammer eliminates
the hazard of swinging a hammer to make up or break down a
hammer union connection.
Figure 1. Safety Hammer Assembly
The pneumatic device is coated inside and out with rust-
resisting oil before leaving the factory. Before using the Safety
Hammer, remove this oil by pouring about 6cc of WD40 or
equivalent cleaning solution into the air inlet and attach the air
hose. Insert a tool into the Safety Hammer and while holding
the tool against a relatively solid object such as a plank or
timber; operate the Safety Hammer for about 4 seconds. Dry
the pneumatic device immediately after cleaning, pour 3 cc of
air tool oil into the air inlet and again operate the Safety
Hammer for 5 seconds to lubricate all working parts.
