Chain 1/2“ x 1/8“

It is strongly recommended to keep the chain clean.

Dirt build-up on the chain will cause excess wear. A

chain lubricant and solvent for normal road bikes

may be used.

Check the lubrication and tension of the chain in reg-

ular intervals. In the middle of its free length the chain

should have a minimum play(3) of 10 mm (1/4 inch).

See ﬁg: Chain adjustments. When the play in the chain

is about 20 mm (3/4 inch) it must be tightened oth-

erwise it will cause abnormal wear of the chain and

chainwheels. Because of this it is always recommend-

ed to keep the chain play as little as possible. Loosen

the hub nut(2) on both sides and tense the chain with

the chain adjuster(1) when needed.

When the chain has become so long that it can no

longer be tightened with the chain adjusters it is worn

out and shall be replaced with a new one.

To adjust or replace the chain remove frame covers if

necessary.

To adjust the chain the hub nuts(2) should be loos-

ened. Loosening or tightening the nuts on the chain

adjusters(1) will then move the hub and axle forward

or backward. Adjust according to above recommen-

dation. Then tighten the nuts on the hub axle again.

See ﬁg: Chain adjustments.

To replace the chain loosen the chain adjuster as much

as possible. Dismantle the chain lock(6) and remove

the chain. Put on a new chain and assemble the chain

lock. The spring of the chain lock should be assembled

with the closed end in the movement direction(5) of

the chain. Use a pair of tongs for dismantling and

assembling the spring(4). See ﬁg: Chain replacement.

NOTE: At assembly the ﬂywheel has to be parallel

with the centerline of the frame otherwise the chain

and chain wheels makes a lot of noise and wears out

rapidly.

Adjust chain adjusters to allow chain play according

to above. Tighten hub nuts ﬁrmly. Put on frame cov-

ers again.
