OPERATION
METAL CUTTING
See Figure 15, page 15.
Many kinds of metals can be cut with the saw. Be careful
not to twist or bend the blades. Do not force. If the blade
chatters or vibrates excessively, use a finer-tooth metal-
cutting blade. If blade heats excessively, use lower speed.
If blade teeth become filled or clogged when cutting soft
metals, such as aluminum, use a coarser-tooth blade or lower
speed. We recommend use of oil when cutting metals to keep
blades cool, increase cutting action, and prolong blade life.
Clamp the work firmly and saw close to the clamping point
to eliminate any vibration of the work being cut.
MAINTENANCE
WARNING:
When servicing use only identical RIDGID
replacement parts. Use of any other parts may
create a hazard or cause product damage.
WARNING:
Always wear eye protection marked to comply with
ANSI Z87.1. Failure to do so could result in objects
being thrown into your eyes resulting in possible
serious injury.
GENERAL 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.
NOTE: FIGURES (ILLUSTRATIONS) START ON PAGE 13 AFTER
FRENCH AND SPANISH LANGUAGE SECTIONS.
When cutting conduit, pipe, or angle iron, clamp work in a
vise if possible and saw close to the vise. To cut thin sheet
materials, "sandwich" the material between hardboard or ply-
wood and clamp the layers to eliminate vibration and material
tearing. By doing this, the material will be cut smoothly. Lay
out your pattern or line of cut on top of the "sandwich."
NOTE: When cutting metal, keep exposed portion of saw
blade clean and free of metal chips by wiping frequently with
an oily cloth. Use extreme caution in disposing of oily cloth
after completion of job to prevent potential fire hazard.
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.
Electric tools used on fiberglass material, wallboard, spack-
ling compounds, or plaster are subject to accelerated wear
and possible premature failure because the fiberglass chips
and grindings are highly abrasive to bearings, brushes,
commutators, etc. Consequently, we do not recommended
using this tool for extended work on these types of materials.
However, if you do work with any of these materials, it is ex-
tremely important to clean the tool using compressed air.
LUBRICATION
All of the bearings in this product are lubricated with a suf-
ficient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
lubrication is required.
