1.
DO NOT perform any crane operations with engine at idle. Operate engine at specified rpm during
performance of ALL operations.
2.
Always keep load as close to crane and ground as possible when swinging boom.
3.
Keep distance between boom nose and load as short as possible to prevent excessive load swing.
4.
NEVER lift load with lift cylinders fully retracted (bottomed).
5.
When lowering or extending boom, let out cable simultaneously to prevent two-blocking boom nose
and hook block.
6.
Always operate crane control levers with smooth, even pressures; never jerk a control lever.
7.
Never suddenly release a control lever to stop a function. Always return lever to neutral in smooth,
even manner.
TRAVELING WITH A LOAD.
WARNING
ONLY MACHINES WITH PUBLISHED "ON RUBBER" CAPACITIES ARE PERMITTED TO TRAVEL
WITH A LOAD.
CAUTION
ONLY TRAVEL WITH A LOAD ON FIRM LEVEL SURFACES AND DO NOT EXCEED 2.5 MPH (4 KM/H).
All load chart capacity ratings are based on the crane being level and in a stationary position. Traveling
with suspended loads entails many variables, i.e., the type of terrain, boom length and angle, momentum
in starting and stopping, etc. Due to these factors, it is impossible to formulate a single stan-dard rating
procedure with any assurance of safety. Thus, before traveling with a load, it is the operators
responsibility to evaluate the conditions and determine the necessary safety precautions. The following
general precautions should be taken at all times.
1.
Position boom over the rear of carrier.
2.
Engage swing set (house) brake.
3.
Govern travel speed suitable to existing conditions.
4
Maintain correct tire pressures.
5.
Avoid sudden starting and stopping.
6.
Provide tag or restraint lines to snub load swing.
