Practice; Crane Commissioning - Kesla 2014 User Manual

* Never leave the crane boom up without supervision!
* When loading is complete, lower the crane firmly against the base and turn off the pump before
driving off.
* Use great caution when attaching or detaching the crane from a vehicle:
* When you are planning to move the vehicle, make sure that there is nobody at the crane's control
position.
* It is prohibited to install further extensions to the crane without the manufacturer's permission.
* Do not use the crane when it is broken
* Use of the crane for towing is prohibited
* Using the crane for lifting of persons is prohibited

5.3.2 Practice

An experienced operator controls several crane movements simultaneously adjusting the various
operating speeds as required. Naturally, the crane's movement speed is reduced when the oil
stream is shared between several cylinders. An experienced operator handles the crane's control
levers calmly and smoothly, avoiding twitches and sudden stops; thus working is safe and effective
and unnecessary repairs are avoided. Considering the crane's sustainability it is preferable that an
inexperienced driver adjusts the pump's output to be low, so it's easier for him/her to avoid sudden
movements. We recommend exploring the crane's characteristics by lifting small weights at first.

CRANE COMMISSIONING

* Make sure that the vehicle's hydraulic system is cleaned before connecting the hoses to the
crane.
* The crane's hydraulic system has been cleaned and test-run at the factory.
* Test loading has been performed at the factory according to SFS EN 12999.
* Check that the hydraulic reservoir is filled, the shut-off valve on the pump's suction hose is open
and the pressure and return filters are installed.
* Always clean the quick connectors first. Always connect the return hose before the pressure hos-
es. Make sure that the quick connectors connect. If the return hose remains accidentally discon-
nected, the control valve may become damaged.
* When starting the vehicle it must not be connected to hydraulic pressure.
DANGER OF TIPPING!
