Spreading sand or salt
The hook stirrer
must
be used when spreading sand, salt or mixed sand-salt.
(See the section on using the hook stirrer).
Information on using the hook stirrer
The hook stirrer is used for spreading sand, salt,
mixed sand-salt or floury fertiliser.
The hook stirrer must not be used for gravel and granular fertiliser.
We recommend placing the hook stirrer in a vertical position when filling
the hopper with the material when spreading wet sticky sand.
Even though high-quality material is used parts of the stirrer (e.g. rubber feed
disc, cast joint) are subject to increased wear when discharging this type of
material.
Maintenance
The hook stirrer can be removed from the drive shaft without tools.
(Turn hook stirrer 1/4 revolution in the direction of rotation of the broadcast disc and pull up.)
To prevent the hook stirrer from sticking to the drive shaft, it should be removed and the drive shaft
greased, at least before extended downtime.
Cast joint
The cast joint of the hook stirrer should also be greased before extended downtime.
Replace worn joints.
Rubber feed disc
Replace rubber feed disc if it is worn. Otherwise the metal disc will damage the hopper.
The wear on the hook stirrer can be greatly reduced by the following measures:
•
Do not exceed the specified PTO speed.
•
Disengage the hook stirrer in case of interruptions in spreading and/or
closed metering slides.
•
Disengage the hook stirrer when the hopper is empty.
•
Recommendation: If the hopper is not completely empty or if it is empty, continue
running at a reduced PTO speed to prevent the stirrer from rattling loudly
and to prevent increased wear on the hopper and hook stirrer.
Never reach into the hopper with the tractor engine running
and the stirrer engaged.
Risk of injury by rotating stirrer.
Always leave the safety screen in the hopper or in the safety position when the
spreader is in operation.
Note the following when correcting faults, during cleaning,
maintenance, repairs and testing:
•
Switch off the PTO shaft.
•
Switch off the tractor engine.
•
Remove the ignition key.
