PTW Series Pneumatic Torque Wrench
PTW Series Safety
The following warnings are specific to the PTW
Series Pneumatic Torque Wrench.
!
DANGER
• Do not place any part of the body between the
reaction arm and the reaction point.
!
WARNING
Failure to observe and comply with the following
precautions could result in death or serious
personal injury. Property damage could also occur.
• Be aware that a nut or bolt that breaks off during
operation of the tool may become a high-velocity
projectile.
• Never exceed the maximum air pressure shown
on the supplied chart.
• Always wear protective headwear, ear protectors,
footwear and gloves (at a minimum, rigger-type
gloves) suitable for safe operation of the tool.
The protective clothing must not interfere with
safe operation of the tool or restrict the ability to
communicate with coworkers.
• Do not place any objects between the reaction
arm and the reaction point. Keep the hoses away
from the reaction points.
• Tightening and loosening nuts and bolts involves
little visible movement. The pressure and loads,
however, are extreme. Keep your hands away
from the fastener being loosened or tightened.
• Keep loose clothing, hair and other items from
being caught in any rotating part of the tool.
!
CAUTION
Failure to observe and comply with the following
precautions could result in minor or moderate
personal injury. Property damage could also occur.
• Make sure the air supply is off prior to attaching
or removing couplings or hoses. Be certain that
all hose couplings are fully connected before
applying air pressure.
• Always use sockets which are designed for use
with powered wrenches.
• Always position the tool for maximum stability.
Make sure reaction points are adequate for the
forces at work during operation of the tool.
• Make sure the reaction point is of a suitable
shape. For example, use an adjacent nut or bolt
as a reaction point.
• The maximum torque output rating of the tool
must always exceed the torque required to
loosen or tighten the nut or bolt.
• Do not drop heavy objects on the hose. A sharp
impact may cause internal damage to the hose.
Applying pressure to a damaged hose may cause
it to burst.
NOTICE
Failure to observe and comply with the following
precautions could result in property damage and/
or void the product warranty.
• Never use the air hoses to carry or move the tool
or the Filter/Regulator/Lubricator (FRL) assembly.
• If the tool is dropped from a significant height,
have the tool inspected before you operate it
again.
• In severe conditions, the tool must be cleaned
and inspected more frequently.
• Be sure to minimize torsional and bending
stresses in the tool and any accessories.
• Avoid striking the tool at any time, even when it
is not under load. Striking the tool could cause
permanent damage to wrench components and
may affect the wrench calibration.
• Always use Enerpac spare parts.
• Ensure that the tool and related equipment are in
good working condition prior to use.
