CLOSED
ACCELERATING
SLOWING DOWN
3. Move the throle lever/rod to approximately 1/4 of its full travel (25% throle), as indicated in the following figure;
ATTENTION: If this value is exceeded (25%), there is
a risk that, when starng the engine, it will have
enough capacity to make the machine work without
the operator being prepared to start operaons, a
fact that can result in accidents or damage to the
machine.
4. To start a cold engine, move the choke lever to the CLOSED posion.
- To restart a warm engine, leave the choke lever in the OPEN posion.
If the choke lever was moved to the CLOSED posion to start the engine, gradually move it back to the OPEN posion as the engine warms up.
Note: This can change its physical appearance and posion depending on the machine, including the direcon for opening or closing, so pay aenon
to the signs containing informaon regarding acons, movements and direcons.
ATTENTION: Step 4 is valid only in cases of cold start, in case of hot start, disregard this step, that is, it is NOT necessary to acvate the choke. In cases
where the engine is at an "average temperature" to the point that it does not fit into any of the starng categories, that is, hot or cold, open the choke
in order to have 50% of its actuaon, soon aer, just follow the instrucons for the other steps as normal.

ATTENTION: This first movement must be smooth for the correct fing of the components shown in the following figures. Once the rods open and
fit into the liming walls, if the movement is sudden and not connuous, the fing may not occur as it should, a fact that compromises the internal
walls of this system, and also reduces the life of the retractable starter rope.
5. Pull the starter rod/handle slightly to correctly fit the internal components unl it offers a slight resistance to movement, as shown in the following
figures;
Discount-Equipment.com
15
6. Pull the starter rod/knob connuously, quickly and firmly to start the engine;
ATTENTION: Both the pulling and returning movement of the retractable starter rod/handle must be firm and connuous, in order to avoid breakage
of internal components. To perform the correct movement, just pull the rod to the posion that offers a lile resistance, which indicates the ideal fit
of the internal components, and from this point on, connue the movement in a connuous, fast and firm way, without sudden movements, the same
is valid for returning the rod to the inial posion, that is, do not release the rod/handle while the rope is stretched out of the housing.
7. When the engine starts, return the choke rod to the “Closed” posion, and move the throle rod to a posion of 50 to 75% of the throle so that
it is connuous;
8. If the engine does not start aer 3 aempts, open the choke slightly to prevent drowning and repeat the enre engine starng process;
9. Let the engine warm up for 3 to 5 minutes before using it under load, that is, in full operaon;
10. Always operate the engine with the throle rod fully open (100%) when the machine/equipment is in operaon.
Turning off the Engine
1. Turn off the throle to the idle posion;

Machine Operaon
Never remove or alter safety guards, as they play an important safety role for the operator. Always check the state of conservaon of the equipment's
protecve shields.
If any of these are damaged or missing, do not use the equipment unl it has been replaced or repaired.
Do not operate the equipment if you are sick, red or under the influence of alcohol.
If the operator finds himself in a risky situaon, the equipment must be turned off immediately and the supervisor or person in charge takes measures to
eliminate these risks. It is necessary to inform the manufacturer of any risk event or accident with the equipment.
Operang the machine:
Aer starng the engine as instructed, hold the operang handlebars firmly with one hand and move the throle to the ACCELERATE posion to acvate the
trowels blades.
Smoothing operaon:
When the concrete is already at the ideal curing stage to receive the trowel's weight, place the equipment over this area. Turn on the equipment and adjust
the blades as previously explained.
Use the lt adjuster to adjust the blades - they must be as close to the concrete as possible and the operator must hold the equipment strong enough to
prevent it from losing its stability.
Guide the blades over the concrete in a circular a circular, backward moon. Under normal condions, it should be able to float in a 30 x 30 meter area in
approximately 15 minutes. This operaon will bring the water to the surface, allowing for a finer finish to the smoothed area.
Maneuver Operaon:
During final finishing, adjust the height of the blade inclinaon to approximately 6 to 10mm. If the blades begin to sink into the concrete, decrease the lt
height.
As the following explanaon shows, it is possible to understand the applicaon of the Power Trowel in the backward direcon.
2. Place the engine switch in the “0” (OFF) posion, turning it counterclockwise;
3. Close the fuel cock by moving the tap level switch to the closed (OFF) posion, being to the le.
NOTE: These starng instrucons are general guidelines only. Consult the engine manual for specific instrucons.

17
VOLVER
• To move the trowel to the le of the operator, li the operang handlebar and to move it to the right, push the handlebar down;
• The best method for finishing concrete is to slowly maneuver the trowel backwards, swiveling the blades from side to side. This will cover any marks that
sll exist in the wet cement;
• Remember! If you stop operang the Power Trowel, step away from the machine, and only when it has stopped completely can you resume using it.
NEVER use the trowel on surfaces that are already dry/cured, as this may damage the blades, and will not produce any troweling effect.
