General Recommendations
Regular maintenance will improve the performance
and extend the life of the dethatcher. Some
adjustments will need to be made periodically
to properly maintain your dethatcher. Follow the
requirements in the Maintenance Schedule.
When performing any maintenance or adjustments
on this equipment, always take proper safety
precautions. Wear safety glasses, and protective
gloves.
This dethatcher's warranty does not cover items
that have been subjected to operator abuse or
negligence. To receive full value from the warranty,
the operator must maintain the dethatcher as
instructed in this manual, including proper storage
as detailed in the Long Term Storage section on
page 8.
NOTE: Once per year you should clean or replace the
spark plug, and clean or replace the air filter on the
FLEX™ Power Base. A new spark plug and clean air
filter ensure proper fuel-air mixture and help your
engine run better and last longer.
Dethatcher Maintenance
Warning! Spring tines may be sharp.
Keep hands and feet away from spring
tines.
Spring Tine Adjustment
Check the spring tine fasteners (hex screw, shoulder
spacer and nut, as well as retention wire) before
each use. Using the dethatcher may, over time,
result in the need to replace the spring tines on the
dethatcher. To remove spring tines:
1. Remove the hex screw (a), shoulder spacer (b)
and nut (c) securing the spring tine from the
top of the tray. See 1 in Figure 5-1.
2. Rotate the spring tine forward. See 2 in
Figure 5-1.

Dethatcher Tray
Due to the difference in weight between the FLEX™
Power Base and the dethatcher add and secure
weight to the dethatcher tray in order to better
balance the unit from front to back.
• Cinder blocks are recommended.
• Maximum recommended weight is 90 lb.

Short Term Storage
Warning! Spring tines may be sharp.
Keep hands and feet away from spring
tines.
It is important to clean the tine assembly after each
use before storing. Debris can quickly accumulate
around the spring tines and retention wire, and
under the tine shield. Keep area around and behind
muffler free from any combustible debris.
• Use a damp cloth to wipe exterior surfaces clean.
• DO NOT insert any objects through cooling
slots on the FLEX™ Power Base.
• Use a soft bristle brush to loosen caked on
dirt, oil, etc.
CAUTION: Improper treatment of dethatcher could
damage it and shorten its life.
Long Term Storage
If you plan to store the dethatcher for an extended
period of time lightly coat spring tines with oil. See
Figure 5-4.
