Assembly Instructions
1. Remove the bar from the box and CHECK THE TIGHTNESS of all bolts and mounting studs.
2. Fit the skids to the top of the bar (figure 2).
3. Fit the drive assembly (A) to the bar (B) using RED
LOCTITE on the two nuts. Ensure washers are fitted correctly (figure 3). If applicable check the oil level in the oil bath.
4. Fit cover mounting bracket (C) to drive unit (figure 4).
Ensure locating pin on bracket fits into the lower of the two holes. Secure the bracket with the nut & bolt provided. If applicable fit the spacers provided under the front cover
5. Fit plastic protection cover to drive unit (figure 4). Nip the bolt tight at this stage but do not overtighten.
6. Fit bracket (D) to plastic cover.
7. Fit brackets (C) and (D) together. This will normally be through the bottom set of holes in bracket (D).
8. Tighten all nuts and bolts on the brackets and cover.
9. Read the manual thoroughly before making any adjustments.

ATTACHING THE BLADE HOLDER
1. Remove the bolt in the lower side of the blade holder
(figure 9).
2. Screw the M8 x 20 bolt provided in the upper part of the blade holder all the way down (figure 10).
Figure 9
3. Install the lock nut that locks the bolt in place (figure 11) and mount the blade holder again (figure 12).
4. Adjust the blade holder (figure 13). See page 6 for more on blade holder adjustment.

Blade Holder Adjustment
Loosen the upper lock nut (A in figure 17).
Adjust the tension screw (B in figure 18) until the blade slides freely between the tooth and blade holder without excessive slack (figure 18).
When the adjustment produces the best motion without binding, tighten the upper lock nut (A in figure 19).
BLADE ADJUSTMENT
To adjust the blades, loosen the blade holder (C in figure
20) and move the blade to the wear blocks (E) operating on the blade holder and tighten the bolts allowing a little slack.

Safety Precautions
During transportation of the machine, or when it is not in use, install the blade guard (A) on the bar (figure 14).
Always wear HEAVY GLOVES to protect your hands whilst working on the equipment.
READ and observe all warning labels on the machine and implements (figure 15).
Always wear appropriate work clothes whilst operating the machine, always wear safety footwear.
DO NOT USE the machine near children or animals (figure
16).
The machine operator is responsible for any damage to persons or property.
Always walk with the machine - DO NOT RUN.
NEVER work on slopes of more than 20 o
and always work across the face of a slope (side to side), NEVER up and down. NEVER use the machine on a bank where there is a possibility of the machine sliding down the slope.
Always disengage the power take-off (PTO) when changing direction or location of operation.
DO NOT replace the blades or attempt to undertake any maintenance of the cutter bar while the engine is running.
ONLY qualified persons should operate the machine.
If any abnormal vibrations occur STOP the engine immediately and visually inspect the machine and implement for any signs of damage.
IMPORTANT: Read all machine and implement manuals thoroughly before using the cutter bar.

Operating Hints
!
IMPORTANT
NEVER USE MORE THAN ¼ THROTTLE
WHEN THE CUTTER BAR IS OPERATING
IMPORTANT: Read all machine and implement manuals thoroughly before using the cutter bar.
Always familiarise yourself with the machine’s operation before commencing work.
Best results are obtained with the engine at a low throttle setting, which enables the bar to cut cleanly and gives less wear and tear on the reciprocating parts, which in turn reduces maintenance.
NB: If you are working on a slope, always work across the slope - never up or down.
On rough terrain, the bar should be raised by the height adjuster skids to prevent the blades from digging into the ground.
WARNING: If any abnormal vibrations or sounds occur, STOP the engine immediately and check the machine and the cutter bar. If you have any concerns contact your supplier.

Blade Replacement
BLADE REPLACEMENT
To replace the blades, loosen the bolts and remove the blade holder (figure 21).
If necessary, first loosen the blade holder (figure 22) and then remove the blade (figure 23).

Replacment of Traction Pin
After every 100 hours of operation check the condition of the blade control pin (A in figure 24) and the ferrule (B).
If replacement is required loosen the block nut (C in figure
24) then slide out the pin (A) and the ferrule (B) and replace them with new parts.
Check the setting screw (G in figure 25) that fixes the steel blade (M) and replace if necessary.
Tighten the screws (V) completely on the steel blade and tighten each setting screw (G) to the same degree until almost all the play has been eliminated on the blade control pin (figure 26).
Finally lock them with conical lock nut (D).

Maintenance Guide
For detailed engine maintenance please refer to engine manufacturers manual.
After every hour of operation stop the engine and remove the spark plug cap. Check engine oil level (recommended oil SAE 10w/40). Before checking the oil level ensure the machine is level.
Remove the gearbox unit dipstick and ensure the oil reaches the top level mark, if necessary top up with API
GL-5 80w/90 gear oil (see Power Unit Owner’s Manual for more details).
Replace the spark plug cap.
Figure 27
CUTTER BAR MAINTENANCE
After every 4 hours of work grease the drive unit at the lubrication points (figure 27).
The oil bath control units contain 1 litre of oil and do not require greasing just periodic checks to ensure proper oil levels.
To check the oil level of an oil bath drive, remove the oscillating safety device (A in figure 28) then remove the oil plug and make sure the oil level is approximately 60mm below the hole.
If the oil level is too low, top up with SAE 80W/90 oil (figure
29) and grease the connection bush (figure 30).
Ensure the cutter bar blades are clean and sharp at all times. After each use wash the cutter bar to remove any grass or soil (figure 31) and check the sharpness of the blades.

Maintenance Guide
After washing lubricate the blade to avoid oxidation. Use an old paintbrush or similar to smear grease over the cutter blades.
Check to ensure all nuts and bolts are well fastened, including those securing the bar to the drive unit and machine implement (figure 32).
Please note that this maintenance programme relates to the attachment only. For maintenance of the gearbox and controls please see the Power Unit
Owner’s Manual.
NOTES:
* Pressure washing machines removes lubricating grease as well as dirt. It is imperative all linkages, especially the gear speed lever detent ball, are kept well greased otherwise they will become difficult to operate and cause damage.
* DO NOT turn the machine on its side for cleaning.
* DO NOT allow maximum engine speed to exceed 3600rpm.
