Maintenance and care
Your GrassHopper is fitted with the latest bi-
cycle technology that does not require much
maintenance.
However, you will have to maintain your bicy-
cle regularly, as it is with other vehicles too.
At least once a year the bicycle has to be tak-
en to a bicycle mechanic for an overall service.
Only this way a long lasting and safe function
of all parts of your bicycle can be guaranteed.
It maintains the value of your bicycle as well as
the fun and the safety while riding for many
years.
Read in this chapter how you can carry out
smaller maintenance and care works between
the services.
For a quick overview of the works to be done
take a look at the warranty pass on
page 60.
Wear and Tear
As on many other vehicles, some parts on a
bicycle are affected by wear and tear.The life-
time expectation of these parts depends on
the intensity and type of use as well as on the
maintenance and care. Please keep in mind that
the process of wear and tear is normal and no
reason for a warranty claim against your deal-
er or HP Velotechnik.
You will find more specific information on
wear and tear in the chapters on the relevant
parts.
Brakes
The brake pads suffer from wear due to fric-
tion and have to be exchanged then. Please
read the manual of the brake manufacturer
carefully.
With rim brakes the rim walls suffer from
wear.When the rims are too worn the tire
pressure can tear up the rim and damage the
wheel - danger! Please have your bicycle me-
chanic check your rims at the latest after the
second brake pad change and exchange them if
necessary.
cable operated (mechanical) brakes
The brake pads of your brakes are worn when
you can pull the lever further and further to
the handlebar before the pads touch the rim.
Rim brakes:When the pads are so worn that
you can't see the cross grooves of the pad
anymore you will have your bicycle mechanic
exchange the brake pads.
To balance the wear of the brake pads you can
tighten the cable with the adjuster barrel
where the cable goes into the brake lever. First
loosen the locknut, then undo the screw so far
that the wheel turns, barely not touching the
pads, hold the screw and tighten the locknut
again towards the brake lever.Take care that
the slot of the adjuster points down so that
no moisture enters from above or the front.
Maintenance and care, Brakes
Caution!
The maintenance works of this re-
cumbent partly require special tools and
skills. Do only work within your limits and,
in the interests of your own safety, do not
go beyond. Should you be uncertain at any
point, get in contact with your local dealer.
Caution!
Damaged cables with single wires
sticking out have to be exchanged immedi-
ately. Otherwise your brake system may fail
- danger! Please take care that the cable
ends are always protected with a cap.
Always keep the cables shortly trimmed.
Leaving too much cable extending past the
cable anchor can result in the cable catching
in the rotor or wheel, which could then be
pulled in the calliper, causing the wheel to
look up.
