GENERAL SAFETY GUIDELINES

Employer/Controller Responsibilities
OH&S legislation places obligations on the employer, or the controller of the Mower, to identify the hazards and control the
risks associated with the use of the Mower in their workplace and to do so in accordance with the manufacturer's instructions.
When purchasing a Mower:
1. Ensure the manufacturer's instructions are provided at the point of purchase.
2. Ensure the Mower conforms to industry safety standards.
3. Discuss your needs with the supplier, to ensure the Mower is compatible with the power of your tractor and is appropriate
for The intended application-consider the speed of your tractor's PTO and its compatibility with the Mower's gearbox.
4. Seek practical advice and instruction from the supplier on the use and limitations of the Mower. If you are hiring, leasing or
borrowing a Mower on a temporary basis, get safe use instructions from the person supplying it.
5. The employer must provide safety instructions to all those involved in using a Mower.
6. A copy of safety instructions must be kept in good condition with the Mower.
Generally, the safety instructions should be the manufacturer's instructions. Any variations from the manufacturer's
instructions must be based on a risk assessment and must not remove any of the safety features nor expose anyone to risks.
Supervision, Instruction and Training
The employer must provide safe systems of work, adequate supervision, instruction and training to all those involved in using a
Mower. They must be instructed in the safe operation of the Mower, including hazards specific to the workplace, including the
terrain, stability of the tractor, working environment and the like. The employer should ensure that everyone achieves a level of
understanding that enables them to safely and competently operate the Mower.
Inspection,Maintenance and Repair
The Mower must be inspected according to the manufacturer's instructions, prior to use. See page 23 for Maintenance
Instructions.
All problems identified must be rectified,prior to use.
The Mower must be maintained according to the manufacturer's instructions.
Replacement parts must be to the original manufacturer's specifications or their equivalent.
Safety signs and decals should be legible,maintained and where necessary replaced. ·Repairs should be carried out by a
competent person.
When suspending the Mower for maintenance or repair, whether attached to the tractor or suspended in another way, adequate
safety stands must be used to prevent inadvertent lowering of the Mower.
Service and Maintenance Safety
Stop engine, set brake, remove ignition key and wait for all moving parts to stop before servicing, adjusting, repairing or
unplugging.
Support the equipment with blocks or safety stands before working beneath it.
Follow good shop practices including:
-keep service area clean and dry
-be sure electrical outlets and tools are properly grounded
-use adequate light for the job.
Use only tools, jacks and hoists of sufficient capacity for the job.

3.PTO Installation
In some cases it will be necessary to shorten the PTO assembly to match your particular tractor. The following procedure
should be used:
1. Check that the driveline is the correct length. The minimum
coupling length (overlap) must be no less than 150mm (6 inches)
in each work position.The driveline travel must still be about
25mm (1 inch) in the maximum coupling (overlap) position.
2. Always couple the two end yokes of the driveline, check that they
are locked in place. To achieve this condition, completely insert
the latch pin into the groove in the PTO shaft on the tractor.
Install the bolt through the yoke and input the shaft on the mixer.
An unlocked shaft will slip out of position, causing notable
mechanical damage and serious injury to anyone nearby. If the
driveline is too long, it should be shortened in the following way:
●Set the machine PTO input shaft at a minimum distance from
the tractor PTO stub shaft, then set the tractor brakes, and
switch the engine off.
●Separate the two halves of the driveline. Install the female part into the tractor PTO and the male part on the
machine PTO, checking that the position is correct by means of the latch pin.
●Place the two halves of the driveline together, keeping them parallel. Using a felt-tip pen, mark the place where the
two halves must be shortened, measuring 1.0 inch from the beginning of each half, as shown in Figure. Double
check before making any cuts. Cut PTO drivelines cannot be returned.
●Raise and lower the Slasher to determine the position with the greatest distance between the PTO shaft and slasher
input shaft. Shut the tractor off, leaving the slasher in the position of greatest distance between shafts. SECURELY
BLOCK THE SLASHER IN POSITION.
●Hold the driveline sections parallel to each other and check for a minimum of 6” (15cm) overlap. If the driveline has
been marked for cutting, the overlap will be the distance between the two marks. If the driveline has less than the
minimum overlap, do not use it. Contact an authorized dealer.
●If the driveline must be cut to a shorter length, clamp it in a
well-padded vise to prevent damage to the shield. Cut off the
shield where it’s marked. Using the removed sections of the
shield as a guide, cut off the same amount from the shaft .
●Repeat the procedure on the other driveline half. Remove all
burrs and cuttings.
●Apply multi-purpose grease to the inside of the outer (female)
driveline section. Assemble the driveline and install on the tractor and the mixer. Pull on each driveline section to be
sure the yokes lock into place. Make certain the driveline shielding is in place and in good condition.
WARNING !
When attaching the PTO yoke to the tractor PTO shaft, it is important that spring-activated locking pins or balls
operate freely and are seated in the groove on the PTO shaft. A loose shaft could slip off and result in personal injury
or damage to equipment.
●Carefully raise and lower the mixer and check to be sure the PTO assembly does not jam . If it does, cut equal
amounts from each half of the PTO assembly. If the PTO driveline assembly contacts the swinging drawbar, damage
will occur to the driveshaft shield and possibly the driveshaft itself (NOT covered under warranty).
●Check the swinging drawbar of the tractor and make sure the PTO driveline assembly will not contact. The swinging
drawbar can be moved forward on some tractors or it can be removed.
Note: This type of damage is NOT covered under warranty, as it is totally under the control and the responsibility of the operator.
