reaches full speed, it could cause the saw to kickback towards you, possibly
resulting in serious injury.

MAKING POCKET CUTS ( Fig. 17)
WARNING: ALWAYS adjust bevel setting to zero before making a pocket
cut. Attempting a pocket cut at any other setting can result in a loss of control of
the saw, which can result in serious injury.
!
1. Adjust the bevel setting to zero, set the blade to the correct blade depth setting, then use
the lower blade guard lever to swing the guard up.
2. While holding the lower blade
guard up by the lever, firmly rest
the front of the saw base flat
against the workpiece with the
rear handle raised so the blade
does not touch the workpiece
(see Fig 17).
3. Squeeze the trigger switch to start
the saw. ALWAYS let the blade
reach full speed, then slowly lower
the blade onto the workpiece until
the base is flat against the
workpiece. AS the blade enters
the material, you MUST release
the lower blade guard lever.
4. After you complete the cut, release the trigger switch and allow the blade to come to a
complete stop. After the blade has stopped, remove it from the workpiece. If the corners
of your pocket cut are not completely cut through, use a hand finishing saw to finish
the corners.
WARNING: ALWAYS raise the lower blade guard with the lever to avoid
serious injury.
!
NOTE: Since the thickness of blades varies, MAKE A TRIAL CUT in scrap material
along the guideline to determine how much, if any, you should offset the blade
from the guideline to allow for the kerf of the blade to get an accurate cut.
Fig. 17
WARNING: NEVER tie the lower blade guard in the raised position. Leaving
the blade exposed could result in serious injury.

WARNING: To ensure safety and reliability, all repairs - with the exception
of the externally accessible brushes - should be performed by a qualified service
technician at a Sears Service Center.
!
It has been found that electric tools are subject to accelerated wear and possible
premature failure when they are used to work on fiber glass boats and sports cars,
wallboard, spackling compounds or plaster. The chips and grindings from these materials
are highly abrasive to electrical tool parts, such as bearings, brushes, commutators, etc.
Consequently, it is not recommended that this tool be used for extended work on any
fiberglass material, wallboard, spackling compound or plaster. During any use on these
materials, it is extremely important that the tool is cleaned frequently by blowing with an
air jet.
WARNING: For your safety, ALWAYS turn off switch and unplug circular
saw from the power source before performing any maintenance or cleaning.
!
WARNING: Always wear safety goggles or safety glasses with side shields
during power tool operations, or when blowing dust. If operation is dusty, also
wear a dust mask.
!
ROUTINE MAINTENANCE
Periodic maintenance allows for long life and trouble-free operation. A cleaning, lubrication
and maintenance schedule should be maintained. As a common preventive maintenance
practice, follow these recommended steps:
WARNING: DO NOT at any time let brake fluids, gasoline, petroleum-based
products, penetrating oils, etc. come in contact with plastic parts. Chemicals can
damage, weaken or destroy plastic, which may result in serious personal injury.
!
MAINTENANCE
1. When work has been completed, clean the tool to allow smooth functioning of the tool
over time.
2. Use clean damp cloths to wipe the tool.
3.
Check the state of all electrical cables.
4.
Keep the motor air openings free from oil, grease and sawdust or woodchips, and store
tool in a dry place.
5.
Be certain that all moving parts that are exposed are well lubricated, particularly after
lengthy exposure to damp and/or dirty conditions.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient amount of high-grade lubricant
for the life of the tool under normal operating conditions. Therefore, no further lubrication is
required.
