1. OPERATING INSTRUCTIONS
1.1 BASIC OPERATION
FUEL
• C-Max has a two-stroke engine that
requires a gasoline-oil mixture.
• Use gasoline with a pump octane
number of 92 or higher .If “knocking” or
“pinging” occurs, try a different brand of
gasoline or a higher octane grade.
• To mix gasoline and oil in a ratio of
33:1. Prepare the fuel mixture in a clean
container fig. 1 , and shake until
thoroughly mixed before filling the fuel
tank.
•
USE A GOOD QUALITY OF
SYNTHETIC 2-STROKE OIL
CAUTION:
To much oil will cause excessive smoking and
spark plug fouling. Too little oil will cause
engine damage or premature wear. Mix fuel
in a ratio of 40 parts gasoline to 1 part oil
(33:1)
•
Vegetable oils separate from gasoline
more easily than mineral oils, especially
in cold weather. It is advisable to use
synthetic oil.
CAUTION:
• Do not mix vegetable and mineral based
oils.
WARNING
• Gasoline is extremely flammable and is
explosive under certain conditions.
Perform this operation in a wellventilated area with the engine
stopped. Do not smoke or allow flames
or sparks in the area where gasoline is
drained or stores and where the fuel
tank is refuelled.

1.2 START ENGINE
WARNING
• Never run the engine in an closed area. The exhaust contains poisonous carbon
monoxide gas that can cause loss of consciousness and may lead to death.
• Attention to start the engine without the reducer provokes the outbreak of the clutch
and can cause injury or damages.
• Never run the engine without propeller.
• The starter attempt can carry to the spin of the propeller and therefore to possible
lesions.
• The motor running emits disturbs electromagnetic
Version manual starter with clutch:
1. Starter engine to warm:
2. Don’t engulf the engine but make sure
the gasoline goes in intake pipe.
3. Insert the Block Clutch System (Fig.1)
4. Grasp the start and pull gently just after
point more hard (try repeatedly to be
sure)
5. Pull whit energy the handgrip without
speed for 3 o 4 and without groped to
start.
6. Pull with energy the handgrip and
speed slightly after first turn of engine.
7. In case of start failed to repeat again
the operation.
8. After starter engine heat it 2/3 minutes
speeding from 3000 to 4000 turns max.

1.3 RUNNING-IN PROCEDURE
Following proper break-in procedure helps censure that some of the most important and
expensive components on your new C-Max will provide maximum performance and service
life. (Also follow proper run-in procedure for a newly rebuilt engine)
1. Do not hold the throttle in one position for more than a few seconds. It’s better
to roll the throttle on and off, without getting too high altitudes and forcing the
engine.
2. Use the motor for features of 10 minutes at a time and to leave to cool it.
3. After 5 hours of use or approximately 20 litres of gasoline the motor should be
broken in.
4. This same procedure should be followed each time

3. MAINTENANCE
3.1 GENERAL SERVICE INFORMATION:
•
•
•
•
•
•
•
Wear gloves and glances when you make the maintenance;
Do not perform maintenance while engine is running. Injury to your fingers, hands or head
may result ;
Perform maintenance on firm, level ground, using hard work plain , and not directly on
chassis;
Always install new gaskets, o-rings, piston pin clips, rings etc .when reassemble some
parts.
When tightening bolts, nuts or screw, start with the larger diameter or inner fasteners, and
tighten them to the specified torque using a criss-cross pattern;
Use genuine Ciscomotors parts when maintenance your C-Max
Clean parts in not-flammable cleaning solvent when disassembling. Lubricate any sliding
surface, o-rings and seals before reassembling.
WARNING
Gasoline or low flash point solvents are highly flammable or explosive and must never be
used for cleaning parts . Fire or explosion could result.
•
After reassembling, check all parts for proper installation and operation
NOTE:
• Specification are listed chapter 2.
3.2 ROUTINE CLEANING
•
•
If the C-Max is only little dirty to clean up it with clean dusts cloth without solvents
If the C-Max is much dirty to clean up it with biodegradable detergents and not with
solvents, lubricate where is necessary.

4. STORAGE
Extended storage such as for winter, requires that you take certain steps to reduce the effects of
deterioration from not use of your C-Max.
Max In addition necessary repairs should be made before
storing your C-Max: otherwise these repairs and clean may be forgotten by the time your C-Max is
removed from storage.

6. ASSEMBLY/DISASSEMBLY STARTER
1. Remove 4 screws (Fig.18)
2. Remove the screw (Fig.20) for to arrive
to the pulley
3. Remove the pulley (Fig.21)
4. Control the screws (Fig.19) are in a good
conditions and locked.
Figure 18
1. Install the pulley and tighten the screw
(pict. 20) to the specified torque
TORQUE : 15Nm( 1,5 kgf/m)
2. Insert the starter in 4 screws (Fig.19)
3. Tighten the screws (Fig.18) to the
specific torque using light locking agent
TORQUE: 12Nm (1.2 kgf/m)

7. REGULATION BELT TRANSMISSION
The tension of belt must be done very carefully
1. Slightly little the 4 fix screws of
bracelet (Fig.32)
2. Insert an Allen key 8 m / m in the seat
(Fig32-1 point 2) and rotate counterclockwise torque of 400 Nm (40kgf / m)
3. Tighten the 4 Allen using the cross
method the specified torque
•
Figure.32
TORQUE: 12Nm (1,2 kgf/m)
Figure 32-1
CAUTION:
Control the tension as Fig.32-2
1. Tension too taut it’s cause of early usury
of bearing
2. Tension too loose it’s cause of exessive
consumpion of belt.
