7 Maintenance and care

IMPORTANT:
Check to ensure that
• No fuel or oil is leaking, and rectify if necessary
• Bolts and nuts are securely fastened, and tighten if necessary
• All moving parts run smoothly, and lubricate if necessary
DANGER!
Clean the implement regularly, particularly in the exhaust and engine area. Otherwise, there is an
increased risk of re.
Comply with the adjustment, maintenance and inspec-
tion tasks and intervals specied in the user manual,
including the information on replacing parts/equip-
ment. These tasks may only be carried out by qualied
personnel. See the maintenance schedule.
Inform operating personnel in advance before carrying
out special work and maintenance work. Name
the supervisors.
Switch the machine on and off in accordance with
the user manual and comply with the instructions on
maintenance work for all work that may affect opera-
tion, production adjustment, conversion or adjustment
of the machine and its safety-critical equipment, as
well as work involving inspection, maintenance and
repair. Cordon off a large area for maintenance work
if required.
The machine must be secured against being switched
back on inadvertently if it is completely switched off
for maintenance and repair work:
-Remove the key
-Afx a warning sign to the starter.
Only carry out maintenance and repair work when the
machine is parked on a level surface with sufcient
load-bearing capacity and when the machine is secured
against rolling away and overturning.
During replacement, individual parts and larger assem-
blies must be carefully attached and secured to lifting
gear such that they do not pose any risks. Only use
suitable lifting gear in technically perfect condition and
load-handling equipment with sufcient load-bearing
capacity. Do not stand or work under suspended loads.
Do not use machine parts as climbing aids.
Keep all handles and steps free from dirt, snow and ice.
Clean oil, fuel or care products from the machine, and
the connections and screw connections in this case in
particular, before starting maintenance/repair work.
Do not use aggressive cleaning agents. Use lint free
cleaning cloths.
Before the machine is cleaned with water, a high-pres-
sure cleaner or other cleaning agents, all openings
which must not allow water/vapour/cleaning agents to
penetrate for reasons of safety or operational function-
ing must be covered over or sealed. Electric motors and
other live components are particularly at risk.
After cleaning, the covers and seals must be completely
removed.
After cleaning, inspect all fuel and oil lines for leaks,
loose connections, areas of abrasion and damage. Im-
mediately rectify any defects that have been identied.
Always retighten screw connections that have come
loose during maintenance or repair work.
If safety devices need to be removed during set-up or
maintenance and repair work, they must be reinstalled
and tested immediately after the maintenance and
repair work has been completed.
Ensure that operating and auxiliary materials and
replacement parts are disposed of safely and in an
environmentally friendly manner.
Electrical equipment on a machine must be inspected/
tested on a regular basis. Defects, such as loose connec-
tions and burnt cables, must be rectied immediately.
When working on high-voltage assemblies, connect
the supply cable to earth after the power has been
disconnected and short-circuit the components, e.g.
capacitors, using an earthing rod.
Never allow combustion engines to run in closed or
conned spaces. The exhaust gases contain poisonous
carbon monoxide gas.
Comply with the regulations which apply to the site
of use in question.
Only carry out welding, open-ame and grinding work
on the machine if this has been expressly approved.
For example, there may be a risk of re or explosion.
Before welding, open-ame and grinding work is
carried out, remove dust and combustible materials
from the machine and its surrounding area and ensure
that there is sufcient ventilation (risk of explosion).
Check all lines, hoses and screw connections regularly
for leaks and signs of external damage. Rectify any
damage immediately. Oil escaping under pressure may
result in injuries and res.
Noise insulation equipment on the machine must be in
the protective position during operation.
Wear the prescribed personal hearing protection.
Observe the safety instructions which apply to the
product when handling oils, greases and other chemical
substances.
Take care when handling hot operating and auxiliary
materials (risk of burning or scalding).
