Chapman MG250 Anleitung Seite 5

A gas strut is fitted as standard to ease lifting of the roller, however a reasonable amount of force is still required in order to do so.
It is recommended NOT to attempt to lift the machine out of work mode with the roller set in the upright position, as shown by the image above
left, and to instead raise the roller to this position after lifting the machine out of work.
The gas strut does a lot of work when lifting the roller, and therefore it is essential that this is maintained. If the gas strut becomes worn, or the
roller becomes heavy to lift, replacement is quick and simple.
Attachment to Towing Vehicle
Before attachment, ALWAYS ensure the following:
•
All safety guards & decals are in good working order and correctly fitted
•
Lubrication points have been lubricated as per scheduled maintenance period
•
The tyres are free of damage and inflated to the correct pressure (0.35-0.55 Bar [5-8psi])
Attaching the Machine
1. Reverse the towing vehicle up to the machine
2. Attach the machine onto the towing vehicle's coupling using either the auto-lock coupling or suitable pin
hitch. Ensure the hitch is securely attached to the towing vehicle
3.
If required adjust drawbar angle for the towing vehicle, this should only need to be done once unless the towing vehicle is changed. The
drawbar should be adjusted so that the main frame of the machine is approximately level with the ground when in work mode.
Safety Notice: ATVs 250cc or under are not due to tractive limitations. Some small ATVʼs may be ok, depending on tyre condition and towing
capacity. Four-wheel drive (if available) should be engaged at all times.
Adjustment
Initial Adjustement
Note: Ensure both tyres operate under the same working pressure (0.35-0.55 Bar [5-8psi])
1. Move the grader to the arena that is suitable for test grading
2. Lower the machine to the ground by raising the transport lever (4), engaging working mode. Adjust the drawbar angle such that the
main frame is approximately parallel to the surface
3. Move forward slowly to assess the grading depth and adjust as necessary.
4. If the grader drags too much material and is hard to pull, the depth limit (3) will need to be adjusted clockwise to limit the working depth.
Raise the transport lever (4), adjust the depth limit (3) as necessary and repeat from step 3. If the grader does not move enough material,
adjust the depth limit (3) anti-clockwise and repeat from step 3.
amending the angle of the drawbar, making the main frame slope upwards towards the drawbar (for greater tine & levelling blade
engagement), or down towards the drawbar (for lesser tine & levelling blade engagement). Furthermore the depth of the tines
themselves can be adjusted up or down if needed.
5. An element of trial-and-error is required to find the best settings for each arena, and the optimum working depth will change through
the year due to variables such as surface temperature, water content etc. However once a base level is established generally the depth
limit (3) can be left in this position so that you can easily grade the arena next time with minimal adjustment.
NOTE: The transport lever should ALWAYS be raised away from the working position to adjust the working depth adjustment screw to prevent
unnecessary cosmetic damage to the axle assembly
If you find the tines are too shallow or too deep this can be altered by
