EC–7C Router Service & Maintenance
Instructions
Operation:
The tool is designed to operate
on 90 PSI air pressure using a 3/8 inch hose
up to 8 feet in length. If additional hose is
required, a 1/2 inch or larger hose should be
connected to the 3/8 inch hose.
Lubrication:
An automatic in-line filter lubricator
is highly recommended to increase tool life as
well as keeping the tool in sustained operation.
If in-line lubricator is not used, the tool should
be lubricated several times daily by disconnecting
the air hose and injecting a few drops of a high
grade No. 10W machine oil in the air inlet.
Disassembly:
Clamp the throttle body EC 1253
in a soft-jawed vise with the tool in a vertical
position. After removing the nose and collet
nut and using a suitable spanner wrench,
unscrew (left hand threads) the bearing retainer
ring. The motor housing EC 9175 may now be unscrewed
from the throttle body with the aid of a strap
wrench.
Bump the rear of the motor housing
lightly on the bench to remove the motor unit
from the rotor. The rotor shaft and related components
may now be pressed out the front of the housing.
The throttle valve EC 9186 may be removed by
driving the throttle lever pin EC 3280 out of
the throttle lever EC 3252. Unscrew the hose
adapter EC 3102 for inspection and cleaning of
the air filter EC 3110.
