1.Safety Operation
1..1 Operator safety
Personal Fall Protection
Personal fall protection equipment (PFPE) is required when operating this machine. If PFPE is required
in job site or in operator's manual, the following rule should be complied with:
All PFPE must comply with applicable governmental regulations, and must be inspected and used in
accordance with the PFPE manufacturer’s instructions.
1..2 Workplace safety
This machine is not electrically insulated and will not provide protection from contact with or
proximity to electrical current.
a) Obey all local and governmental regulations regarding required clearance from electrical power
lines. At a minimum, the required clearance contained in the table below must be followed. Allow
for platform movement, electrical line sway or sag, and beware of strong or gusty winds;
Table 1-1 Required clearance
No. Line Voltage Required Clearance
1 0 to 50KV 3.05 m 10ft
2 50 to 200KV 4.60 m 15ft
3 200 to 350KV 6.10 m 20ft
4 350 to 500KV 7.62 m 25ft
5 500 to 750KV 10.67m 35ft
6 750 to 1000KV 13.72m 45ft
b) Allow for platform movement, electrical line sway or sag, and beware of strong or gusty winds;
$-(%RRP/LIW2SHUDWRU¶V0DQXDO 3DJH

c) Keep away from the machine if it contacts energized power lines. Personnel on the ground or in the
platform must not touch or operate the machine until energized power lines are shut off.
Do not operate the machine during lightning or storms.
Do not use the machine as a ground for welding.
Tip-over hazard
Occupants, equipment and materials shall not exceed the maximum platform capacity.
Table 1-2 Rated load
Maximum platform capacity
Unrestricted range of motion 250 kg /550 lb
Maximum occupants 2
a) Do not exceed the maximum platform capacity;
b) Do not attach a platform rated at 250 kg /550 lb to machines with any other rated load. See the
serial label for the maximum rated capacity;
c) The weight in options and accessories (such as pipe, panel bracket and welder) will reduce rated
platform capacity and must be factored into total platform load.See the decals with the options and
accessories;
d) If using accessories, read, understand and obey the decals and instructions with the accessory;
e) Do not raise or extend the boom unless the machine is on a firm, level surface.
Do not depend on the tilt alarm as a level indicator. The tilt alarm sounds in the platform only when the
$-(%RRP/LIW2SHUDWRU¶V0DQXDO 3DJH

machine is on a severe slope.
If the tilt alarm sounds when the platform is raised, use extreme caution. Identify the condition of the
boom on the slope as shown below. Follow the steps to lower the boom before moving to a firm, level
surface. Do not rotate the boom while lowering.
a) If the tilt alarm sounds with the platform uphill:
1) Lower the upper boom;
2) Lower the tower boom;
3) Retract the upper boom.
b) If the tilt alarm sounds with the platform downhill:
1) Retract the upper boom;
2) Lower the tower boom;
3) Lower the upper boom.
Do not raise the boom when wind speeds may exceed 12.5 m/s (28mph).
If wind speeds exceed 12.5 m/s (28mph) when the boom is raised, lower the boom and do not continue
to operate the machine. Do not operate the machine in strong or gusty winds. Do not increase the
surface area of the platform or the load. Increasing the area exposed to the wind will decrease machine
stability.

a) Use extreme care and slow speeds while driving the machine in the stowed position across uneven
terrain, debris, unstable or slippery surfaces and near holes and drop-offs;
b) Do not drive the machine on or near uneven terrain, unstable surfaces or other hazardous
conditions with the boom raised or extended;
c) Never attempt to use the machine as a crane;
d) Do not push the machine or other objects with the boom;
e) Do not contact adjacent structures with the boom;
f) Do not tie the boom or platform to adjacent structures;
g) Do not place loads outside the platform perimeter;
h) Do not alter or disable machine components that in any way affect safety and stability;
i) Do not replace items critical to machine stability with items of different weight or specification;
j) Do not replace factory-installed tires with tires of different specification or ply rating;
k) Do not use air-filled tires. These machines are equipped with foam-filled tires. Wheel weight is
critical to stability;
l) Do not use the platform controls to free a platform that is caught, snagged, or otherwise prevented
from normal motion by an adjacent structure. All personnel must be removed from the platform
before attempting to free the platform using the ground controls;
m) Do not modify or alter an aerial work platform without prior written permission from the
manufacture. Mounting attachments for holding tools or other materials onto the platform, toe
boards, or guard rail system can increase the weight in the platform and the surface area of the
platform or the load;
n) Do not push off or pull toward any object outside of the platform.

a) Do not place or attach fixed or overhanging loads to any part of this machine;
b) Do not place ladders or scaffolds in the platform or against any part of this machine;
c) Do not transport tools and materials unless they are evenly distributed and can be safely handled by
person(s) in the platform;
d) Do not use the machine on a moving or mobile surface or vehicle;
e) Be sure the tires are in good condition and the lug nuts tightened, besides the tightening torque
should be 300N/m(20.2 lb/ft);
f) Do not drive the machine on a slope that exceeds the maximum uphill, downhill or side slope
rating of the machine. Slope rating applies only to machines in the stowed position.
Table 1-5 Maximum slope rating, stowed position
Maximum slope rating, stowed position
Platform uphill 45% (24°)
Platform downhill 45% (14°)
Side slope 25% (14°)
Note: slope rating is subject to ground conditions with one person in the platform and adequate
traction. Additional platform weight may reduce slope rating.

Fall Hazards
a) Occupants must wear a safety belt or harness in accordance with governmental regulations. Attach
the lanyard to the anchor provided in the platform;
b) Do not sit, stand or climb on the platform guard rails. Maintain a firm footing on the platform floor
at all times;
c) Do not climb down from the platform when raised;
d) Keep the platform floor clear of debris. Use extreme care while entering or exiting the platform. Do
not enter or exit the platform unless the machine is in the stowed position. Enter or exit the platform
through the gate only. Face the machine and ensure "three-point contact" with the machine (two
hands and one foot, or two feet and one hand) while entering or exiting the platform.
$-(%RRP/LIW2SHUDWRU¶V0DQXDO 3DJH

Collision Hazard
a) Be aware of limited sight distance and blind spots when driving and operating;
b) Check the work area for overhead obstructions or other possible hazards;
c) Be aware of crushing hazards when grasping the platform guard rail;
d) Be aware of the boom position and tail swing when rotating the turntable;
e) Operators must comply with employer, job site, and governmental rules regarding use of personal
protective equipment.

Do not lower the boom unless the area below is clear of personnel and obstructions.
Limit travel speed according to the condition of the ground surface, congestion, slope, location of
personnel, and any other factors which may cause collision.
Observe and use the color-coded direction arrows on the platform controls and drive chassis for drive
and steer functions.
Do not operate a boom in the path of any crane unless the controls of the crane have been locked out
and/or precautions have been taken to prevent any potential collision.
No stunt driving or horseplay while operating a machine.
Body Injury Hazard
a) Do not operate a machine with a hydraulic oil or air leak. An air leak or hydraulic leak can
penetrate and/or burn skin;
b) Improper contact with components under any cover will cause serious injury. Only trained
maintenance personnel should access compartments.
Suggestion: access by the operator is only advised when performing a pre-operation inspection. All
compartments must remain closed and secured during operation.
