IMPORTANT:
Maintenance and adjustment should ONLY be done after the following has
occurred:
tractor’s engine has been stopped and ignition key has been taken out,
all rotating parts have come to complete standstill (NOTE: raking tines will rotate for
several minutes after engine is turned off),
Never tamper with or remove safety devices on the machine or make them inoperable.
Before starting work and periodically thereafter, replace any damaged, missing and/or worn
tines and holders.
When driving on public roads always comply with local traffic regulations, especially those
concerning warning lights.
When the rake is lifted for repair on 3-point linkage, it should be secured against falling by
mechanical support or by chain.
The bolts and other fasteners have to be periodically checked and, if necessary, tightened or
replaced. DO NOT work with damaged or worn fasteners.
Never lift the rake on tractor linkage when the drive is operating and the rotors are in motion.
When operating the rake, the tractor should always be equipped with operator protection that is
required by laws and regulations.
Rotating spring tines and other rotary elements pose danger to health and life of persons
remaining within the machine working range. Do not touch any moving machine parts.
Never start the rake when the rotors are off the ground.
Before you start the tractor make sure that all drives are turned off and the levers that turn the
hydraulics are in neutral position.
Never leave tractor’s engine running without supervision. Before you leave the tractor, turn off
the engine and remove the key from tractor’s ignition.
DO NOT operate the rake when driving the tractor backwards.
Permissible inclination of the rake on a slope when working and during transport is 8°.
Exceeding this incline can result in rake tipover.
Never stand between tractor and rake unless tractor and rake are secured against moving by the
tractor’s brake.
If any maintenance must be done under an elevated rake, it must be blocked or otherwise
secured against falling.
When the parts of the rake need replacement, use only original spare parts as described in the
spare parts list. Pay particular attention to PTO shaft’s guards and rake’s and tractor’s spline
shaft guards.
Hydraulic hoses are potentially very dangerous. Do the following to minimize any hazards:
Hydraulic hoses should be periodically checked and if any damage to the hoses have
occurred or if they have been used more than 5 years, replace with new ones.
Never use scotch tape to repair hydraulic hoses.
When connecting hydraulic hoses to tractor’s hydraulic connectors, make sure that
the tractor’s or rake’s hydraulic system is not under pressure.
The rake should be stored under a roof and in a way as to not be hazardous both to people or
animals.
In the event of an accident involving this rake in a field or on a road, follow all applicable first
aid procedures and contact SaMASZ technical service.
Rake should be kept clean, so as to avoid danger of fire.
The operator is not allowed to leave the tractor while driving.
