1. The correct use of Electric stacker
Allow only based on this manual use this electric stacker.
Described in this manual stacker walking electric stacker, with electric
operation to control the height of lifting function. High car is in order to ascend
and reduce the transportation load to the desired lifting height and design.
Improper use may result in personal injury or damage to the machine.
The operator / operating company needs to ensure the correct use, while
ensuring the high car pile by only have been trained and authorized to use.
The stacker to flat on the firm foundation, using intact, plane and appropriate
surface. The car to +5 C to +40 C Room temperature environment and indoor
light load is applied without crossing the permanent disabilities or pits. Ban
operating on a slope. When the load center, the goods must be placed
approximately in high car pile of.
It is strictly prohibited to lift or carry personnel. As a carrier, the goods must be
reduced to the lifting point (<118in).
Prohibited in lifting using this car carriage plate loading or unloading slope
bench. Rated load in the load curve and the nameplate label. The operator must
pay attention to these warnings and safety instructions. The operation must be a
minimum of 50 lux illumination.
Changing:
Any of the vehicle load ratings, affect the stability or safety operation of
change or change, must obtain prior car.
Written approval of a native business or authorized by the manufacturer or its
successor. This includes the effects of the changes, such as: brake, steering,
Increase the visibility and mobile accessories. When the manufacturer or its
successor approved modify or change, load curve, label, The identification
mark, operation and maintenance manuals will be corresponding changes.
The damage of the vehicle does not follow these instructions and cause will
lose the warranty Vehicle.
