Assembly - Murray 425615x50A Instruction Book

ASSEMBLY

All fasteners are in the parts bag. Do not discard
any parts or material until the unit is assembled.
WARNING: Before doing any as-
sembly or maintenance to the
mower, remove the wire from the
spark plug.
NOTE: In this instruction book, left and right
describe the location of a part with the oper-
ator on the seat.
NOTE: Illustrations and pictorials begin on
page 2.
NOTE: To assemble the following loose
parts, use the fasteners shown at full size in
Figure 25.
How To Install The Front Wheels
(Figure 1)
Use a knife and cut the four sides of the con-
tainer. Install the front wheels (1) in the con-
tainer.
NOTE: Use a piece of wood about 4 feet (1.25
meters) long to raise the front of the tractor.
If a piece of wood cannot be found, get
another person to help lift the tractor. Be
careful, do not let the tractor fall.
1. Raise the front of the tractor. Set a support
(block of wood) under the tractor.
2. Make sure the valve stem (2) is to the out-
side of the tractor. Slide the front wheel (1)
on the spindle (3).
3. Fasten each front wheel (1) with washer (4)
and cotter pin (5). Bend the ends of the
cotter pin (5) appart to keep the front wheel
(1) on the spindle (3).
4. After the front wheels (1) are installed, lift
the tractor from the support. Roll the tractor
off of the container.
5. If your tractor has hub caps (6), install the
hub caps (6). Make sure the washers (4)
hold the hub caps (6) in place.
How To Assemble The Mower Housing
(Figure 22)
1. Move the blade rotation control (1) to the
DISENGAGE position.
2. Move the lift lever (2) to the level adjust-
ment position.
WARNING: The lift lever is spring
loaded. Make sure the lift lever is
locked in the LEVEL ADJUSTMENT
position.
3. Attach the front hanger (9) to the deck with
the fasteners. See illustration "H".
4. Push the mower housing under the right side
of the unit.
5. Put the mower drive belt (7) around the
stack pulley (8). See illustration "G".
NOTE: Make sure the "V" side of the
mower drive belt is against the stack
pulley. Also, make sure the mower drive
belt is not twisted.
6. Attach the front hanger (9) to the axle sup-
port. See illustration "F".
7. Make sure the mower drive belt (7) is be-
tween the stack pulley (8) and the two belt
guides (10). See illustration "G".
8. Attach the suspension links (4) to the lifter
assembly. Fasten with the hair pins and
washers. See illustrations "A" and "B".
F-030744L
9. Attach the right and left adjuster arms (3) to
the suspension brackets. Fasten with the
hair pins and the washers. See illustrations
"C" and "D".
10. Attach the extension spring (5) to the
blade control rod (6). See illustration "E".
11. Move the blade rotation control to the EN-
GAGE position. Make sure the mower drive
belt is inside all the belt guides.
12. Make sure the mower housing is level. See
the instructions on "How To Level The Mower
Housing".
13. Attach the gauge wheels (12) to the axle
bolts (11) with the fasteners. See illustration
"I".
14. Check the operation of the blade rotation
control. See the instrucions on "How To Ad-
just The Blade Rotation Control".
Check The Tyres
Check the air pressure in the tyres. Tyres with
too much air pressure will cause the unit to ride
rough. Also, the wrong air pressure will keep the
mower housing from cutting level. The correct
air pressure is: Front Tyres 0,97 BAR (14 PSI),
Rear Tyres 0,69 BAR (10 PSI). The tyres were
over inflated for shipment.
Check The Level Of The Mower Housing
Make sure the level of cut is still correct. After
you mow a short distance, look at the area that
was cut. If the mower housing does not cut level,
see the instructions on "How To Level The
Mower Housing" in the Maintenance section of
this instruction book.
How To Install The Seat (Figure 2)
1. Carefully remove the plastic bag from the
seat (1).
2. Align the holes in the seat hinge (2) to the
holes in the seat (1). Fasten the seat (1) to
the seat hinge (2) with the fasteners (4) and
(5).
3. Check the operating position of the seat (1).
If the seat (1) needs to be adjusted, loosen
the two wing bolts (5). Slide the seat (1) for-
ward or backward along the seat adjusting
holes (3). Tighten the wing bolts (5).
How To Assemble The Steering Wheel
(Figure 3)
1. Make sure the front wheels point forward.
2. Slide the cover (3) over the steering post
(2). Make sure the collar of the cover (3) is
on top.
3. Slide the steering wheel (1) onto the steer-
ing post (2).
4. Attach the steering wheel (1) to the steer-
ing post (2) with screw (4) and washer (6).
5. Some models have an optional insert (7) in
the parts bag. Attach the insert (7) to the
centre of the steering wheel (1).
Maintenance Free Battery (Figure 4)
IMPORTANT: Before you attach the battery
cables to the battery, check the battery date.
The battery date tells if the battery must be
charged.
1. Check the top of the battery (1) for the loca-
tion of the battery date.

2. If the battery (1) is put into service before
the , the battery cables can be attached with-
out charging the battery (1). See "How To
Install The Battery Cables".
3. If the battery (1) is put into service after the ,
the battery (1) must be charged. See "How
To Charge The Maintenance Free Battery".
How To Charge The Battery (Figure 4)
WARNING: When you charge the
battery, do not smoke. Keep the bat-
tery away from any sparks. The
fumes from the battery acid can cause an
explosion.
1. Remove the battery (1) and battery tray (3).
2. Remove the protective caps from the battery
terminals.
3. Use a 12 volt battery charger to charge the
battery (1). Charge at a rate of 6 amperes
for one hour. If you do not have a battery
charger, have an authorized service centre
charge the battery.
4. Install the battery (1) and battery tray (3).
Make sure the positive (+) terminal (4) is on
the left side.
How To Install The Battery Cables
(Figure 4)
WARNING: To prevent sparks, fasten
the red cable to the positive (+) ter-
minal before you connect the black
cable.
1. Remove the protective caps from the battery
terminals.
2. Slide the terminal cover (2) onto the red
cable (5). Fasten the red cable (5) to the
positive (+) terminal (4) with the fasteners
(6) and (7).
3. Fasten the black cable 8 to the negative (-)
terminal with the fasteners (6) and (7).
How To Prepare The Engine
NOTE: The engine was shipped from the fac-
tory filled with oil. Check the level of the oil.
Add oil as needed.
See the engine manufacturer's instructions for
the type of petrol and oil to use. Before you use
the unit, read the information on safety, oper-
ation, maintenance, and storage.
WARNING: Follow the engine manu-
facturer's instructions for the type of
petrol and oil to use. Always use a
safety petrol container. Do not smoke when
adding petrol to the engine. When inside an
enclosure, do not fill with petrol. Before you
add petrol, stop the engine. Let the engine
cool for several minutes.
NOTE: Actual sustained horsepower will like-
ly be lower due to operating limitations and
environmental factors.
Important! Before You Start Mowing
r
Check the engine oil.
r
Fill the fuel tank with petrol.
r
Check the level of the mower hous-
ing.
r
Check the air pressure of the tyres.
