Maintenance - Ryobi BIW180 Owner's Operating Manual

CAUTION:
To prevent gear damage, always allow the chuck
to come to a complete stop before changing the
direction of rotation.
To stop, release switch trigger and allow the coupler to
come to a complete stop.
WARNING
Make sure the bit is secured in the coupler
before using the impact wrench. Failure to do so
could cause serious personal injury.
WARNING
Do not drive a screw where there is likely to
be hidden wiring behind the surface. Contact
with a "live" wire will make exposed metal parts
of the tool "live" and shock the operator. If you
must drive a screw where hidden wire may be
present, always hold tool by insulated gripping
surfaces (handle) when performing the operation
to prevent a shock to the operator, as seen in
figure 5.
CAUTION:
The impact wrench is not designed to be used as
a drill.
INSTALLING AND REMOVING SOCKETS
See Figures 4.
Use only sockets designed for impact wrenches. Always
select the correct size impact socket for nuts and bolts.
Using the wrong size socket may damage the nut or
bolt and cause the fastening torque to be inaccurate or
inconsistent.
Remove the battery pack.
■
Push the socket onto the drive shank until the detent
■
pin locks it into place.
To remove the socket, pull it away from the drive
■
shank.
OPERATING THE IMPACT WRENCH
See Figures 5.
Proper fastening torque may be determined by the
kind of bolt, the size of the bolt or the material or the
workpiece. It is helpful to perform a test operation to
determine the proper fastening time for the nut or bolt
you are using. While performing the test, make note of
the speed selection.
Hold the tool pointed straight at the nut or bolt.
■
Depress the switch and fasten for the proper
■
English
fastening time.
After fastening, always check the torque with a torque
■
wrench.
NOTE: Do not use this tool to install lug nuts on
wheels without a torque limiting device. Doing so
could result in galled or broken lugs.
IMPACT TIME
Many variables exist that will cause the available torque
of the fastener to vary considerably. The optimum impact
time is approximately 6 seconds.
NOTE: Using a universal joint or extension bar may
reduce the fastening force of the impact wrench and
require longer fastening time.
DRIVING OR REMOVING SCREWS
See Figures 5 - 6.
Place the rotation selector in the correct position for
■
the operation.
Hold the impact driver with one hand.
■
Place the bit on the screw head and slowly depress
■
the switch trigger. Start the bit slowly for more control.
As the screw is driven, impacting will begin.

MAINTENANCE

WARNING:
When servicing, use only identical Ryobi
replacement parts. Use of any other parts may
create a hazard or cause product damage.
WARNING:
Always wear safety goggles or safety glasses
with side shields during power product operation
or when blowing dust. If operation is dusty, also
wear a dust mask.
WARNING:
To avoid serious personal injury, always remove
the battery pack from the product when cleaning
or performing any maintenance.
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, oil, grease, etc.
WARNING
Do not at any time let brake fluids, gasoline,
petroleum-based products, penetrating oils, etc.,
