Adjustment Of Cutting Height; Adjustment For An Appropriate Height; Safety Precautions - Dolmar EM-41 Manual De Instrucciones

5. ASSEMBLY
5-1 ASSEMBLY THE FOLDING HANDLE
A) Fix the lower handlebars into the unit body with
locking knobs. (Fig. 2 - 5)
B) Release the upper handlebars for folding. Connect the
upper handle and the lower handle with the locking
knob. (Fig. 6 & 7)
C) Position the cable over the handle shaft. Clamp it
around the middle of lower handle by the cable clamp
so that the cable is fixed on the outside of the
machine. Otherwise the cable may be pinched by
opening/closing the rear cover or forced by folding the
upper handle. (Fig. 8)
5-2 ASSEMBLY THE GRASS CATCHER
1. To fit: Raise the rear cover and hitch the grass catcher
on rear of mower. (Fig. 9 & 10)
2. To remove: Grasp and lift the rear cover, remove grass
catcher.
6. ADJUSTMENT OF CUTTING
HEIGHT
Apply outward pressure to disengage lever from rack.
Move lover forward or back to adjust height.
The height (the blade to the ground) can be adjusted from
20 mm (the lowest position) to 75 mm (the highest
position), 5 height positions (20 mm/32 mm/44 mm/
60 mm/75 mm). (Fig. 11)
WARNING: Make this adjustment only when the
blade is stopped.
7. ADJUSTMENT FOR AN
APPROPRIATE HEIGHT
1) Back out the locking knob which fixed the lower
handle, refer to Fig. 12.
2) Refer to Fig. 13, move the lower handle up and down,
adjust it to the proper height.
There is 3 adjusting height to be choose on this type
lawn mower; at 1 height, lower handle to the ground is
highest., 3 height is the lowest.
3) Adjusting to the proper height, then fix the lower
handle by the locking knobs.
WARNING: The left side and right side of lower handle must adjust to the same height.

8. SAFETY PRECAUTIONS

a) Always operate with the deflector or grass catcher in
the correct position.
b) Always stop the motor before removing the grass
catcher or adjusting the height of cutting position.
1) Before mowing, remove all foreign objects from the
lawn which may be thrown by the machine. While
mowing, stay alert for any foreign objects which may
have been missed. (Fig. 14)
2) Never lift the rear of the mower while starting the
motor or during normal operation. (Fig. 15)
3) Always ensure that the ventilation openings are kept
clear of debris.
4) Never place your hands or feet underneath the
underpan or into the rear discharge chute while the
motor is running. (Fig. 16)
9. STARTING
Before connecting up the lawn mower to the electric
power supply, make sure that the mains supply voltage is
230 V – 50 Hz. When the lawn mower power on, the
indicator light will turn on (Fig. 17).
Start the motor as follows (Fig. 18).
a) Press the safety push-button (1).
b) And meanwhile, pull the switch handle (2),and keep it
in grasp.
c) Push the lawn mower manually when the motor is
running. If you release the switch handle, the motor
will stop.
CAUTION: The blade starts turning as soon as
the motor is started.
WARNING: Cutting elements continue to rotate
after the motor is switch off.
CAUTION: Determine the maximum permissible
system impedance Zmax (0.330Ω) at the interface point of
the user's supply, declare Zmax (0.330Ω) in the
equipment instruction manual and instruct the user to
determine in consultation with the supply authority, if
necessary, that the equipment is connected only to a
supply of that impedance or less.
10. BLADE
The blade is made of pressed steel. It will be necessary to
reshape it frequently (with a grind wheel).
Ensure that it is always balanced (an unbalanced blade
will cause dangerous vibrations). To check for balance,
insert a round rod through the central hole and support
the blade horizontally. (Fig. 19) A balanced blade will
remain horizontal. If the blade is not balanced the heavy
end will rotate downwards. Reshape the heavy end until
the blade is currently balanced. (Fig. 20) To remove the
blade (2), unscrew the blade screw (3). (Fig. 21 - 23)
Check the conditions of the fan(1), and replace any parts,
which are damaged. (Fig. 21)
When reassembling, make sure that the cutting edges
face in the direction of the motor rotation. The blade screw
(3) must be tightened to 20 -25 Nm torque.
WARNING: For service, replace the blade with:
DOLMAR 263001427 only.
11. EXTENSION CORDS
You should only use extension cords for outdoor use,
PVC (H05VV-F) or rubber cord (H05RN-F) ordinary duty
with a cross sectional area not less than 1.5 mm
