5. Preparation for use
5.1 Assembly
The high pressure sprayer may only be used
after complete assembly and after the carrying
straps have been adjusted correctly!
To facilitate packing and transport, the spray
wand (17) and trigger handle (15) are not
attached to the pressure hose (14).
Fasten the pressure hose (14) to the trigger
handle (15) by tightening the hex. Nut (20).
5.2 Adjustment of carrying straps
Adjust the length of the carrying strap with the
buckle (21).
The strap is shortened by moving the buckle
upwards. Move the buckle downwards to
lengthen the strap.
The carrying straps are correctly adjusted when
the back cushion of the machine is resting firmly
and securely against the back of the operator.
Do not adjust carrying straps while the machine
is carried on the back.
5.3 Prior to first use and after
extended storage periods
Prior to using the engine driven high pressure
sprayer for the first time and after extended
storage periods we recommend that you check
the correct operation of the complete machine.
Also check all parts and hoses which carry fuel
and chemical liquid for any leakage. This should
be done before you mix the chemical solution.
After reading the manual thoroughly test the
machine as described in the following
paragraph.
Observe all safety instructions while
testing the machine.
Test run:
Fill the liquid tank with approx. 5 litres of water
after carrying out a successful visual check of the
machine. Fill the fuel tank with the correct fuel
mixture as described in section 6 "Fuelling " and
start the high pressure sprayer as described in
section 8 "Starting engine / Stopping engine"
for a test run. Check all parts and hoses which
carry fuel or chemical liquid for leakage. Check
the efficient operation of the throttle lever (8),
the operating handle (15), pressure gauge (16)
and the stop button (9).
Hint: To get a feel for the machine and to gain
confidence in the high pressure sprayer we
suggest you carry out several spray trials
with water only at various pressure
settings.
Note: The pressure gauge will only provide a
pressure reading when the operating
handle is in open position during the
spraying process.
If irregularities, leakages, visual damage (even
on the carrying frame), limited function or
incorrect adjustments are detected, do not start
any spray operations but have the high pressure
sprayer checked by a specialized service centre.

All about fuel
ENGLISH 10
6. All about fuel
6.1 Fuel information
The power for this machine is supplied by a high
performance two stroke engine operated with a
petrol / oil mixture (petrol + oil = fuel mixture)
or with a special fuel mixture for two stroke
engines available from specialists. The fuel
mixture can be made up with standard lead-free
petrol or with lead-free premium grade petrol.
The minimum octane rating for petrol is 92 ROZ.
Unsuitable petrol or deviations in the mixing
ratio may lead to serious engine damage!
Avoid direct skin contact with petrol and
avoid inhaling petrol fumes - health
hazard!
6.2 Mixing ratio
Always use a fuel ratio of 25 : 1 (4%) for the
first five tank fillings.
After that we recommend a ratio of 50:1 (2%)
with the use of special two-stroke oil "Castrol
Super TT" which is offered by our company.
With the use of other brand two stroke oils we
recommend a ratio of 25:1 (4%).
Never store fuel mixture longer than 3 - 4 weeks.
