Start-Up; Working - Stiga BP 375 Operator's Manual

Action
Release the throttle
control lever (Fig. 4.A) /
throttle adjuster (Fig. 4.B)
Move the throttle regulator
and machine stop lever
to "STOP" (Fig. 4.C)
If any of the results fail to match
the indications provided in the tables
below, do not use the machine! Take
it to a service centre to be checked
and repaired if necessary.

6.3 START-UP

IMPORTANT A label (fig. 2) is placed on the
machine that summarizes the start up main steps.
The label is a quick guide and it does not
replace the procedures specified below.
1. Adopt a firm and well-balanced position;
2. Make sure that the blower tube is not
directed towards any bystanders or debris;
IMPORTANT To avoid breaking the starter
rope, do not pull the whole length of it or let
it slide along the edge of the cable guide
hole. Release the starter handgrip gradually,
to prevent it flying back uncontrollably.
IMPORTANT Never wind the
starter cable around your hand.
6.3.1 Startup from cold
A "cold" start of the engine means
starting it after at least 5 minutes from when
it was switched off or after refuelling.
1. Rev the engine by moving the
throttle regulator lever (Fig. 4.B)
just beyond half stroke.
2. Engage the choke by moving the
lever to position «C» (Fig. 5.C).
3. Press the primer device control button (Fig.
5.D) 10 times to help start the carburettor.
4. Hold the machine firmly on the ground
with one hand, in order not to lose control
of the machine during startup (Fig. 6.B).
5. This machine is equipped with EASY-
START. Constantly pull the start up handle,
do not tug (the start-up occurs towards the
end of the stroke). Pull a few times, until
you hear the engine start to tick over.
Result
The control automatically
and rapidly returns to
the idle position.
The rotor rotates
at minimum speed
and the blower tube
expels little air.
The engine stops.
The rotor stops and
the blower tube does
not expel air.
6. Move the choke control to
position «B» (Fig. 5.B).
7. Pull the starter grip until the
engine starts as normal.
8. Allow the engine to tick over for at
least 1 minute to warm it up.
9. Disconnect the choke control (Fig. 5.A),
moving the lever to position «A».
10. Move the throttle regulator lever (Fig.
4.B) to minimum to disengage revving
and allow the engine to run idle.
IMPORTANT If the choke handgrip is
pulled repeatedly with the starter on, it may
flood the engine and make starting difficult.
If the engine floods (see paragraph 14.5).
6.3.2 Warm start
When hot starting (immediately
after stopping the engine):
1. Follow points 1 - 3 - 4 - 6 - 7 - 9 - 10 in
the previous procedure (par. 6.3.1).
6.3.3 Using the harness straps
The harness straps must be used
after starting the machine.
The harness and straps must be adjusted
to suit the operator's height and stature.
1. Wear the harness like a rucksack (Fig. 7.A).
2. Close the red clip buckles on the
left side and at the waist.
3. The belts must be tightened so that the load
is evenly distributed on the shoulders.
4. To support the weight of the blower
tube, connect the coupling (Fig. 7.B)
to the control handgrip support (Fig.
7.C), and close the black clip buckle
on the right shoulder (Fig. 7.D).

6.4 WORKING

When performing work, the machine
must always be held firmly with the right
hand on the control handgrip (Fig. 15).
6.4.1 Adjusting the speed
It is always advisable to set the speed of the rotor
depending on the type of material to be removed:
– low blowing speed to move light material
and small branches on the lawn;
– medium blowing speed to move grass and
light leaves on asphalt or packed soil;
– high blowing speed (throttle control pressed
as far as possible) for heavier material,
such as fresh snow or bulky rubbish.
