Maintenance; Important - Murray 1695797 Manual Del Operador

Start The Engine
1. (Figure 5) Before each use, remove
debris from the debris screen (3). Debris
can cause the engine to overheat. Wipe
the debris screen (3) with a cloth or
paper towel.
2. (Figure 10) Move the throttle control
lever (1) forward to the START or FAST
position.
3. (Figure 9) To start a cold engine, push
the primer button (1) five times. Wait
two seconds between each push of the
primer button (1).
NOTE: Do not use the primer to start a
warm engine.
4. (Figure 10) Firmly hold the recoil starter
handle (2) with your right hand.
5. Pull back sharply on the recoil starter
handle (2). DO NOT allow the starter
rope to snap back. Let the starter rope
slowly rewind as you hold the recoil
starter handle (2).
NOTE: If engine fails to start after three
pulls, push the primer button two times and
again pull the recoil starter handle.
WARNING: Never leave the trimmer
unattended while the engine is
running. Wait for the trimmer lines to
stop rotating.
WARNING: Never run the engine
indoors or in a poorly ventilated area.
Engine exhaust contains carbon
monoxide, an odorless and deadly gas. Keep
hands, feet, hair and loose clothing away
from the trimmer and any moving parts on
the engine. Avoid the muffler and
surrounding areas. Temperatures may
exceed 66°C (150°F).
Trimmer Tips
WARNING: Debris such as sticks,
gravel or rocks, can be thrown with
sufficient force to cause personal
injury or property damage.
• Set the throttle control in the FAST
position. If the weeds or grass are tall
and thick, operate the trimmer at a slower
walking speed.
• Frequently clean the underside of the
trimmer to remove any grass buildup.
• If the trimmer lines become too short, it
will take longer to complete the job. If the
trimmer lines are worn to less than half
their original length, change to a new
trimmer line. "See How To Change The
Trimmer Line" in the Maintenance section.
• Do not trim on excessively steep slopes. If
a slope is difficult to stand on, do not trim.
Do not trim on slopes when the ground is
slippery or wet. Trim across the face of a
slope, not up and down.
• Trimming may be done at slower engine
speeds especially when trimming
around flowers, shrubs, and small trees.
Operating at slower speeds will also
reduce engine noise and vibration at the
upper handle.

MAINTENANCE

NOTE: Illustrations and pictorials begin on
page 2.
Engine Maintenance
Use the following maintenance section to keep
your unit in good operating condition. All the
maintenance information for the engine is in
the engine manufacturer's instructions. Before
you start the engine, read this book.
WARNING: Before you make an
inspection, adjustment (except
carburettor), or repair, disconnect
the wire from the spark plug.
Lubricate The Jackshaft Assembly
(Figure 11)
A grease fitting (1) is provided to lubricate
the jackshaft assembly. Use a grease gun
with automotive type grease to lubricate the
jackshaft assembly.
Proper Care of the Trimmer Line
(Figure 12, 13, 14)
For the best performance, use a heavy gauge
3.3mm diameter (0.130 inch) trimmer line
(1). Cut the length of the trimmer line (1) to
52cm (20.5 inches). Do not allow the length
of the lines to vary more than one inch. This
is important to make sure the trimmer head is
balanced and does not vibrate.
IMPORTANT: To extend the life of the
trimmer line (1), keep the trimmer line moist.
If not kept moist, the nylon trimmer line
(1) will become dry and brittle. Keep extra
trimmer line (1) in a can of water. The line
will then stay flexible and easy to change. A
flexible line will also last much longer.
Change The Trimmer Line
When the trimmer line becomes worn to half
the original length, replace the trimmer line as
follows:
1. Stop the engine. Wait for all moving parts
to stop.
2. (Figure 12) Remove worn trimmer line
(1) from line retainer (3).
3. First, thread the ends of the new trimmer
line (1) through the outside loops.
4. (Figure 13) Next, take the ends of the
line, cross over the line retainer (3), and
thread the ends through the center hole.
5. (Figure 14) Then, check to make sure
that the ends of the line are even.
Adjust The Height Of The Handle
(Figure 15)
Use the knobs (1), on each side of the handle
(2), to adjust the height of the handle.
1. Hold the handle (2) with one hand and
loosen both knobs (1) until the ratchet
teeth (3) are disengaged. Do not remove
the knobs (1).

2. Move the handle (2) up or down to the
desired position, then align the ratchet
teeth (3). Make sure both sides of the
handle (2) are level.
Tighten the knobs (1).
3.
Replace The Drive Belt
To replace the drive belt, see an authorized
service center.
Storage
WARNING: Do not remove petrol
while inside a building, near a fire, or
while you smoke. Petrol fumes can
cause an explosion or a fire.
When the trimmer is put in storage for thirty
days or more, follow the steps below to make
sure the trimmer is in good condition the
following season.
Prepare The Trimmer For Storage
WARNING: Do not remove petrol
while inside a building, near a fire, or
while you smoke. Petrol fumes can
cause an explosion or a fire.
1. Drain the fuel tank.
2. Let the engine run until it is out of petrol.
3. Drain the oil from the warm engine. Fill
the engine crankcase with new oil.
4. Remove the spark plug from the cylinder.
Pour one ounce of oil into the cylinder.
Slowly pull the recoil-start grip so that the
oil will protect the cylinder. Install a new
spark plug in the cylinder.
5. Clean the dirt and debris from the cylinder
cooling fins and the engine housing.
6. Clean the bottom of the trimmer.
7. Completely clean the trimmer to protect
the paint.
8. Put the unit in a building that has good
ventilation.
