Metal Cutting; Maintenance - Ryobi ERS800RG Owner's Operating Manual

Cutting into electrical wiring can cause the blade, the
blade clamp, and the saw bar assembly to become
electrically live. Do not touch metal parts when cutting
into a wall; grasp only the insulated surfaces on the
tool. Make sure hidden electrical wiring, water pipes,
and mechanical hazards are not in the blade path when
cutting into a wall.

METAL CUTTING

See Figure 7.
You may cut metals such as sheet steel, pipe steel rods,
aluminum, brass, and copper with your saw.
Observe the following tips when metal cutting.
 Be careful not to twist or bend the saw blade.
 Do not force the tool.
 Use cutting oil when cutting soft metals and steel.
Cutting oil also keeps the blades cool, increases
cutting action, and prolongs blade life.
 Never use gasoline since normal sparking of motor
could ignite fumes.
 Clamp the workpiece firmly and cut close to the
clamping point to eliminate any vibration of the work.
When cutting conduit pipe or angle iron, clamp the
workpiece in a vice if possible and cut close to the vise.
To cut thin sheet material, "sandwich" the material
between hardboard or plywood and clamp the layers
to eliminate vibration and material tearing.
 Always keep firm pressure on the base to hold it
securely against the workpiece.

MAINTENANCE

GENERAL
All other parts represent an important part of the class
II insulation system and should be serviced only by a
qualifi ed service technician.
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types
of commercial solvents. Use clean cloths to remove dirt,
carbon dust, etc.
Do not at any time let brake fl uids, gasoline, petroleum-
based products, penetrating oils, etc. come in contact
with plastic parts. They contain chemicals that can
damage, weaken or destroy plastic.
It has been found that electric tools are subject to
accelerated wear and possible premature failure when
they are used on fi berglass boats, sports cars, wallboard
or plaster.
WARNING
WARNING
LUBRICATION
All of the bearings in this tool are lubricated with a
suffi cient amount of high grade lubricant for the life of
the unit under normal operating conditions. Therefore, no
further lubrication is required.
Keep extension cords away from the cutting area and
position the cord so that it will not get caught on lumber,
tools, etc., during cutting operation.
Check extension cords before each use, if damaged,
replace immediately. Never use tool with a damaged
cord as touching the damaged area could cause
electric shock resulting in serious injury.
Extension cords suitable for use with your saw are
available at your nearest service center.
Save these instructions for future reference.
