Sharpening of cutting blades
TRAPP shredders leave factory with temperate
cutting blades, prolonging cutting durability.
Sharpen the cutting blades when the edge is
dull. Sharpen the side indicated only (figure 3),
trying to keep its original inclination. Whenever
sharpening, be careful to remove the same
amount of material from each cutting blade to
keep balance and to avoid vibrations of the
axle unit. The cutting blades shall be substituted
whenever optimum sharpening is no longer
possible.

Hammers
Hammers are provided with 4 dented corners
which position can be changed as they wear
out (figure 5).
To change position of hammers or to substitute
them, remove the axle (1) counterpins and
the lock (2) (figure 6). Remove them through
the opening in the green crop feeder. When
removing them, to avoid unbalance and
vibration of the shredder, always observe the
position of the separating rings. Be careful not
to mix the hammer sets (sides).

Tichtening of screws
Due to the impact and constant vibrations
caused by chopping and grinding of
materials, it is a natural tendency for
screws to loosen.
Check them periodically, and if necessary
tighten the loose screws. Be careful not to
overtighten as they may strip.

Always turn off shredder and unplug
