LUBRICATION
See Figure 21.
This tool has been properly lubricated and is ready to use.
However, it is recommended that the gears be lubricated
only with Mobil SHC 636 Oil.
Always check the oil level before using this tool, using the
dipstick provided.
n Unplug the tool.
n Place the base of the saw on a horizontal surface.
n Remove the oil plug using a 6mm hex wrench.
n Tip the saw up and let oil drain out into an appropriate
oil container.
n Replace the oil using a small funnel (less than 1/4 in.
spout). Take care to let air out while putting new oil in to
avoid spilling.
n Fill only with Mobil SHC 636 Oil. (Available as a replace-
ment part.)
n Fill the gear case until the oil level is between the two
marks on the dipstick. Do not overfill. If the level of oil
raises above the second mark on the dipstick while the
base is on a level surface, overheating may occur.
n Replace the oil plug with a 6mm hex wrench. Do not
overtighten. The O-ring under the head should be com-
pressed slightly. Overtightening will cause the o-ring to
unseat and not seal properly.
Note: With a new saw, change the oil following the first
ten hours of use. This will prolong the life of the tool by
removing the gear particles from the oil when the gears
are breaking in.
BRUSH REPLACEMENT
See Figure 22.
The tool has externally accessible brush assemblies that
should be periodically checked for wear.
n Unplug the tool.
n Remove the brush cap with a torx screwdriver. The brush
assembly is spring loaded and will pop out when you
remove the brush cap.
n Remove the brush assembly (brush and spring).
n Check for wear. If worn, always replace in pairs.
Do not replace one side without replacing the other.
