The end of the heating season is the best time to perform
annual maintenance. Rust and corrosion can form much
faster in the high humidity of summer, so cleaning your
VF 3000 will prevent those damages.
1. Remove all coal from the hopper
2. Remove all ashes
3. Remove and clean ue pipe
4. Check chimney and clean if necessary
5. Remove hopper and check for rust at bottom edges.
If rust is found, remove it with a le or sandpaper then
paint the area with spray paint available at your Harman
dealer.
6. Check the feeder for rust and corrosion where the hop-
per ts into it.
7. Check pusher block to be sure it moves freely. This
can best be done by shaking the adjuster rod. If it does
not move freely, it should be removed and cleaned. Also
remove any rust or corrosion from the area where the
pusher block slides and spray with WD-40 or other rust
preventing spray. To remove pusher block, remove cover,
wing nut, adjuster and adjuster tube. Remove motor mount
with motor in place and cord still attached. Swing pusher
assembly up as high as it will go. Remove feed indicator
from side with allen wrench. Now the pusher block can be
removed. To reinstall, just reverse procedure. If the pusher
block cannot be removed, call your Harman dealer.

When left stand-
ing for long periods with wet coal, the pusher block
will rust and corrode, causing it to stop. If the stoker
is then turned “on”, damage to the pusher assembly
and feed motor will result. This will be considered
neglect and will void the warranty on those parts.
If the unit has not been burned for a period of time,
always check to see if moving parts are free before
using. This can best be determined by shaking the
adjuster rod.
