(1) Press the power button shortly to light the power indicator, then
the laser transmitter starts.
(2) If the power light flashes after the laser is activated, it shows that
the battery is low and you shall replace it.(Pic 4.4)
(3) Please try to charge the battery after it runs out completely and
charge it fully once, not halfway off. (First charging shall be 12hr,
after that, charging 8hr is all right. Pease unplug the power cord after
the battery is fully charged to avoid damage to battery and

2. Starting procedures
(I) Installation and starting of transmitter and receiver
(1) Installation of transmitter（Pic 5.1、5.2）
Pic 5.1 Adjustment of Transmitter
1) Placed the tripod near the construction site, smooth and
unobstructed, and adjust the three feet to make the bubble on the
top platform in the black circle.

2). Fix the transmitter to the tripod platform
3). Adjust the height of the tripod platform (≥1.8m) and press the
switch to start the transmitter. (Note: After a few seconds the
transmitter will automatically adjust the leveling, the laser turns off,
and then turns on automatically after about 30s).
(2) Receiver installation

Pic 5.3 Installation of receiver
1) As it is shown in Pic 5.3, two receivers are fixed to the two
aluminum poles.
2) In the case of the transmitter is installed, aim first handheld
receiver at transmitter height, make the bottom end of the rod
touch just touch the concrete surface, and then adjust the height
of the receiver so that the center position of the transmitter laser
beam alignment.
3). Put the handheld receiver on one side of the blade
perpendicularly, adjust electric cylinder manually until the
digital display of handheld receiver is "0", that is, the handheld
receiver lever aligned with the central position of
the laser beam emitter again. (Note that both of the sides shall be
adjusted as above-mentioned.)
4) Finally adjust the two receivers on the aluminum poles to aim
their center at the transmitter beams.
(II). Generators starting
1) Open fuel plug，see Pic 5.4

3) Pull throttle switch on generators （turn on it according to the
specific temperature. Pull it less if temperature is higher.
Pic 5.6 Throttle switch of Generations
4) Pull the starter handle slowly until you feel a repulsive force, then
pull out quickly! After starting the generators, still grasp the handle,
and then let it recover the naturally.
5) After the starting the generators, let the throttle switch recover
slowly. (Don’t shut the choke completely suddenly if the generators
are cold or the temperature is low, otherwise, generators is easily

(IV). Use the function keys to operate the machine
（Key introduction
in page 10）
(V). Clench the security armrest in the left hand to control the
machine walking. （Emergency circumstances, loose the security
armrest then the machine will stop waling，then use the urgent stop
switch to stop the machine and the electric parts, after that, shut off
the generator）See picture 5.8、picture 5.9
