Safety Information
• Pay attention to any rotating parts
before starting cleaning and mainte-
nance work. They represent a risk of
crushing!
• Suitable tools must be used for
cleaning and maintenance work.
• The vehicle must be inspected by a
recognized technical expert in re-
spect of operational safety, within
the terms of the applicable accident
prevention laws, at reasonable inter-
vals (we recommend at least once a
year) and following modification or
repairs .
• Spare parts must comply with the
minimum technical requirements
stipulated by the manufacturer! This
is ensured by the use of original
spare parts.
• Only use the rotary brushes and side
brushes recommended by the manu-
facturer (refer to Technical Data).
The use of other rotary brushes and
side brushes could impair safety.
• The vehicle must be switched off pri-
or to cleaning or servicing it or to re-
placing parts. The key must be
removed from the key switch.
• The dirt hopper must be cleaned reg-
ularly to prevent the accumulation of
bacteria.
• The vehicle is splashproof (IPX3).
It is not permitted to clean the vehicle
with a pressure washer or steam
blaster.
• When transporting the vehicle, the
vehicle must be switched off.
• If the Hako-Jonas 1500 is jacked up
with a jack, it must be properly sup-
ported.
• No persons may be on the Hako-Jo-
nas 1500 when it is jacked or raised.
• When changing wheels, the vehicle
must be additionally secured from
rolling away by placing wheel chocks
against the wheels.
Always change wheels on level, sol-
id ground, where possible.
• Do not remove or replace tires or re-
pair one on a rim. Always go to a
proper workshop for work on tires
and rims because they have special-
ly trained personnel and special
safety tools.
• Do not carry out any welding, drilling,
sawing or grinding work on frame
parts. Damaged parts may only be
replaced by specialist workshops ap-
proved by Hako.
• Only use original fuses. Using fuses
which are too powerful could dam-
age the electrical installation and
lead to fires.
• Always disconnect the negative pole
of the battery when working on the
electrical installation.
• Never leave the batteries in a dis-
charged state but recharge them as
soon as possible.
• Only refill distilled water.
When the cells are in good condition,
never refill the battery acid.
• To prevent current leaks, always
keep the battery clean and dry, pro-
tect it from soiling by metallic dust,
for example.
• Battery acid is very corrosive (keep
out of reach of children).
Wear protective goggles when con-
trolling the acid level. In the event of
acid splashing in the eyes, rinse
them with water for approx. 15 min-
utes and seek medical attention im-
mediately.
Always wear appropriate protective
clothing when handling the battery
(e.g. protective gloves, finger stalls).
Never use an open flame (risk of ex-
plosion).
• When installing or removing the bat-
