of this operator’s manual, so there is no doubt about management before using the equipment
for the first time. If any hesitation, ask your Trejon dealer about advise. It is forbidden to use the
equipment if user don’t know the risk factors at handling, and don’t know how to act in an
emergency situation.
Read, observe and understand meaning of all safety-, use-, warning- and position- symbols at
machine and in user manual.
Safety is the primary concern in the design and manufacture of our products. Unfortunately our
efforts to provide safe equipment can be wiped out by a single careless act of an operator.
In addition to the design and configuration of equipment, hazard control and accident prevention
are dependent upon the awareness, concern, prudence and proper training of personnel
involved in the operation, transport, maintenance and storage of equipment.
Allow only properly trained personnel to operate the equipment.
The machine is intended only for outdoor use.
Management. Learn how to operate the machine and how to use the controls properly before
operating the machine.

damage to the implement or tractor.
Secure the working area. Unauthorized persons, particularly children, are not allowed near the
machine while it is running or is being repaired. Before backing up, look behind carefully.
Pay attention to the injury and damage that can be caused by material thrown by machine
during operating, therefore clear area of stones, branches or other debris that might be thrown,
causing injury or damage. Take care never to aim the snow outlet towards people, animals or
buildings.
The rotating parts of this machine have been designed and tested for rugged use. However,
they could fail upon impact with heavy, solid objects such as steel guard rails and concrete
abutments. Such impact could cause the broken objects to be thrown outward at very high
velocities. To reduce the possibility of property damage, serious injury, or even death, never
allow the cutting blades to contact such obstacles.
Machines protective equipment. Do not operate the machine if not all safety guards and
shields for moving parts are in place and in good condition.

Stability. The machine should not be mounted on a tractor with insufficient front shaft /back
shaft weight when the tractor becomes unstable and difficult to operate. When using a unit, a
minimum 20% of tractor and equipment weight must be on tractor front wheels. Without this
weight, tractor could tip over, causing personal injury or death. The weight may be attained with
a front end loader, front wheel weights, and ballast in tires or front tractor weights, read the
tractor’s instructions manual for more information.
In extremely uneven terrain rear wheel weights, front tractor weights, and/or tire ballast should
be used to improve stability.
Operating machine. Be careful and reduce the speed when working on uneven surfaces.
Watch for holes, roots, rocks or other hidden objects. Do not drive near the edge of a gully,
ditch or stream bank. When mowing over uneven terrain, observe the type of terrain and
develop a safe mowing pattern.
When driving in slopes:
Operate the machine up and down steep slopes, not across slopes, to prevent the tractor from
tipping. Avoid sudden stops and starts, slow down before changing directions on a slope. Pass

Attach the machine at a hard level surface.
Attach tractors lifting arms to lower connection points at machine, and there after the top link,
(choose connection points that make lifting arms and top link as parallel as possible, all to make
machine levelled during lifting)
Turn of tractor’s engine and apply the hand brake.
Adjust the length of the PTO shaft. Pull the shaft apart, and fit the end with the shear pin and
mounting flange on to the tractor. Check that the shaft does not bottom out in any position,
(min. play 30mm) and that the sliding part is sufficiently seated in the cuff part (min. 300 mm)*.
If not, shorten the shaft. See the instructions that came with the shaft, (trim any cutting edges of
, to avoid damages on pipes when telescoping). Try to attain longest possible shaft overlap. Be
extra careful with shaft overlap when using hydraulic top link, when this equipment can make
quick changes at measure. Note that usually the shaft is shorter when mounting at the front
than when mounting at the rear.
*Alternative for PTO-shafts shorter than 1000mm, use at least half of maximum overlap.
Duty rpm’s and rotational directions for drive shafts 1-3/4” Z6
When used on a reversing tractor and when mounted on the front, the shear bolt clutch must
always be closest to the tractor. A wrongly mounted PTO shaft can result in a breakage of the

3.3 Before starting up
Before starting up, following items must be checked.
Check the screws and bolts at the machine and tighten if necessary. See table with
recommended torque settings in section “Service and maintenance”.
Check that all protective devices are undamaged and correctly attached to the equipment.
Lubricate the machine (see section ”Service and maintenance”).
Check the oil level in the gearbox. The oil should reach the lower part of the glass (see section
“Service and maintenance”). The gearbox is filled with oil SAE 80W/90 API GL4/GL5, Industrial
gear oil ISO VG 220.
Adjust height of scraper steel with support pads, and machine tilt with top link (see section
“Adjustments”)
Check that no objects have wrapped themselves around moving parts.
Perform a trial run of entire machine.
3.4 Adjustments
Warning!
No work is allowed unless the equipment is safely secured (don’t completely rely on
tractors 3-point connection).
Be careful when undoing the pierced rod of flap control, crushing hazard!
At any time when performing repairs and maintenance, the engine must be switched off
and the PTO shaft disconnected. Withdraw the ignition key from the switch.
Support pads
The height of the equipment is adjusted with two supporting pads located at the back. The
angle of the equipment is adjusted with the top-link. This determines the how well the
equipment follows the variations in the surface. If the equipment is angled forward, it is easier
for it to cut through packed snow and ice. A suitable basic adjustment when the machine rest on
the support pads, is that the wearing edge of the scraper steel is 10mm above ground. Aim at
keeping the machine levelled during work.
The supporting pads are to be adjusted as the wearing edge is being worn down. The
supporting pads are adjusted by undoing the mounting screws, and mount them in other holes.
