Starting The Engine - Shindaiwa 502s Manual Del Operador

Bar Oil (continued)
Oil Pump Adjustment
Guide bar and saw chain lubrication is auto-
matically provided by an adjustable-rate oil
pump designed to operate whenever the
clutch drum rotates. A temporary increase in
oil flow rate is often desirable when cutting
hardwoods or large-diameter softwoods, and
can be provided as follows:
1. Stop the engine and verify that the
engine stop switch is in the "OFF"
position.
2. Place the saw on its side, with the
clutch cover facing up.

Starting the Engine

WARNING!
This chain saw is equipped
with a fast idle feature for ease of
engine starting. When the fast idle is
set, the saw chain will rotate when
the engine starts! Rotating saw chain
can cause serious injury. Clear a safe
work area before starting the engine.
NOTE:
This engine ignition system is controlled
by a two-position "ON-OFF" switch
labeled "I" for ON and "O" for OFF
located near the rear handle.
IMPORTANT!
This chain saw is equipped with a throt-
tle trigger lock out system designed to
prevent unintended throttle activation.
This system requires the operator to first
depress the throttle lock out lever on top
of the rear handle to release the trigger
from the engine idle position.
Engine Start:
1. Move the ignition ON-OFF switch to
the ON position.
2. COLD ENGINE ONLY: Completely
close the choke by pulling the choke
control out to the fully extended posi-
tion. This motion will automatically
engage the "fast idle" setting.
3. WARM ENGINE: Pull the choke con-
trol out to its fully extended position
and then push the choke control all the
way in again. This motion will automati-
cally engage the "fast idle" setting.

3. Use a screwdriver to turn the oil flow
rate adjustment screw:
a. Clockwise to decrease bar and chain
lubrication.
b. Counter-clockwise to increase bar
and chain lubrication.

4. Place the saw upright on the ground.
5. Secure the saw by stepping on the
inside of the rear handle with the right
foot and firmly grasping the front han-
dle with the left hand.
6. Grip the starter handle with the right
hand and pull slowly until starter
engagement is felt.
7. With the starter engaged, pull the
starter upward. Repeat until the engine
either attempts to start or starts.
8. When the engine attempts to start or
starts, push the choke control in if pre-
viously set. If the engine does not con-
tinue to run, pull the starter until the
engine restarts then immediately press
and release the throttle lever to disen-
gage the fast idle.

Never release the starter grip with
the starter rope extended. Always
hold on to the grip during engine
start and return the starter grip back
to the starter housing slowly as the
starter spring retracts the cord.
If the engine fails to start, repeat the
starting procedure setting the choke
control appropriately for either a cold
or warm engine. If the engine still fails
to start, refer to the section, "Starting a
Firm Grip
Flooded Engine."
