OPERATION / ADJUSTMENT
DANGER
The product must only be put into operation if no defects are found. It is crucial that defective parts are replaced before the product is used again. Check the safety equipment and the safe condition of the product: Check all parts to make sure that they fit tightly. Check whether there are any visible defects: broken parts, cracks, etc.
Regular removal of thatch is critical to the maintenance of a healthy lawn. Thatch is a layer of stems, clippings, runners, roots and leaves that have not decayed. Excessive thatch prevents air, water and fertilizer from reaching the roots. The de-thatcher effectively dislodges excessive thatch from your lawn. Read these instructions to help avoid improper adjustment and operation.
Correct adjustment of the tine shield and spring tines is important for effective performance. Refer to the following steps for the proper adjustment before operating the de-thatcher.
Move the towing vehicle onto a level surface, such as a driveway or garage floor and attach the tine de-thatcher to the vehicle hitch. See Figure 10.
To adjust the spring tine shield, lower the de-thatcher into the operating position using the lift handle. Loosen the two hex nuts and carriage bolts which fasten the rear of the hitch mount arm to the hitch arm mount brackets. Adjust the tin shield until it is level and both the front and rear spring tines are in contact with the ground. Re-tighten the hex nuts. See Figure 10.
Vary the vehicle's forward speed until the best dethatching action is achieved.
For best results, use a crisscross pattern on your lawn.

ADDING EXTRA WEIGHT
If the de-thatcher appears to be jumping during use, extra weight (max 70lbs/31.75kg) should be added to the tine shield.
Attach and secure weights (Concrete blocks are recommended) to each side of the tine shield using rubber tie down straps.
DANGER
Vehicle braking and stability may be affected with the attachment of this machine to your garden vehicle.
Always operate up and down a slope, never across the face of a slope.
Do not work on slopes greater than 10°.
Drive slowly & carefully, especially when turning and on uneven ground.
Do not tow this equipment on a highway or any other public thoroughfare.
MAINTENANCE
LUBRICATE
Maintenance spray or multi-purpose grease can be applied to the wheel axle prior to long-term storage.
CLEANING
After each use thoroughly wash the machine with a stiff brush.
STORING
Before storing, ensure that the machine is clean and dry.
Store in a dry or protected area and coat exposed metal with light oil when not in use.
CHECK ALL NUTS, BOLTS AND FASTENING
Before each use check all fastenings are tight & secure.
APPEARANCE
If rust appears on the shield or spring tines, sand lightly and coat with enamel paint.
NEVER EXCEED LOAD CAPACITY
To avoid damaging the spreader, never exceed the rated load capacity of 45.5kg (100lb)
ONLY USE MANUFACTURER APPROVED PARTS
If a part needs replacing, only use the manufacturer’s original parts. Non-original replacement parts will invalidate your warranty and may result in a safety hazard or poor operation.
