GENERAL SAFETY INSTRUCTIONS
1. Read through this Owner's Manual carefully before using the Access Platform for the
first time. The Access Platform shall never be operated by an operator who is not familiar
with the operating and safety instructions. Store the Owner's Manual in it's own
compartment. ALWAYS keep the manual with the Access Platform.
2. The operator must be at least 18 years of age and have reasonable operating
experience of Access Platforms
3. Kesla XS 240 is fitted with the following fail-safe safety limit switches:
- Support position of the outriggers
- Ground sensing of outriggers
- A limit switch sensing the transport position of the boom in the transport support
- In the platform, a limit switch preventing the collision of the platform and the jib
boom
- Between the boom and the turntable, a limit switch sensing the boom position
4. The emergency lowering system comprises an electrical pump in the turntable, control
valves in the turntable and the platform, and control buttons. Detailed instructions can be
found on page 41.
5. Avoid lifting the platform too close to live electrical cables. The minimum safe distance
to cables with different voltage is shown in a decal located on the platform.
6. Always use a yellow flashing warning light when working on streets with busy traffic.
The working zone shall be fenced to avoid risks. Also observe the relevant traffic
regulations concerning the working site.
7. When driving the Access Platform, the boom shall always be supported in the transport
position. Drive using the bypass switch only when it is necessary when climbing a steep
slope or in difficult terrain, where the platform may hit ground or an obstacle.
8. A maximum of two (2) persons with tools and supplies are allowed on the platform at the
same time, however, so that the total load does not exceed 230 kg (506 lbs). When
moving the Access Platform, there should be only one person in the platform due to
traction power.
9. Use the Access Platform only when the ouriggers are properly extended. Use extra
boards under the outriggers whenever required. Make sure that an outrigger does not slip
on the surface of the extra board and that the extra board withstands the weight of the
outrigger. On icy surface, attach calks or bolts to the outrigger plates. Calk holes have
been provided in the sole plates. For the tightness of different soil types, refer to the soil
tightness table on page 38.
Keep in mind that even asphalt may yield!

any other device. Do not swing or jump in the platform.
15. Do not throw down objects from the platform. Make sure that nothing can fall down.
16. Use ear protection when operating the Access Platform from the ground operating
station, because the sound intensity exceeds 84 db (A). When operating the Access
Platform from the platform, the sound intensity is less than 84 db (A), and the use of ear
protection is not obligatory.
17. Always when you operate the Access Platform indoors or in a place with poor
ventilation, the engine shall be used only for moving the Access Platform. Try to improve
ventilation. Risk of intoxication! The Access Platform may optionally be equipped with a
mains current pump unit for operation indoors (240V / 50Hz).
18. Do not use the Access Platform as a crane or elevator for transporting goods or
persons between different levels or floors. When using the Access Platform, observe the
environment to avoid collisions with fixed or moving obstacles.
19. Do not deactivate a safety device. Repair it or have it repaired by a competent
maintenance personnel before using it again.
20. Ensure that the area below the platform is clear of all personnel and obstructions
before lowering the platform.
21. To ensure safe and trouble-free functioning of the Access Platform, keep it free from
snow, ice and other impurities.
22. Be very careful when handling fuels, lubricating and hydraulic oils as well as lubricating
greases of the Access Platform. Avoid skin contact with these substances. Risk of
exposure!

28. Check the functionality of the load control system every day before starting the work.
See pages 17 to 19 for checking instructions.
If the lifting radii are over or well below the permitted values, please contact an
authorised service shop.
The Access Platform must not be used before the load control has been set
correctly.
29. SAFETY INSTRUCTIONS FOR HANDLING A LEAD BATTERY
1. The electrolyte in a lead battery is diluted sulphuric acid. Several metals and organic
substances are corroded by sulphuric acid. Always wear goggles, gloves and protective
clothing when working with batteries. Any electrolyte splashed on skin should be removed
immediately with plenty of fresh water. If electrolyte gets into eyes, they should be flushed
for at least ten minutes. Immediate medical attention required.
2. Batteries generate hydrogen and oxygen gases during normal use. Together they form
an explosive mixture. All local battery systems containing energy more than 15 kWh
should be stored in a separate, efficiently ventilated battery room. The materials of the
battery room should be selected so that they prevent static electricity and consequent
sparks. The safety of a battery room is also enhanced by protective ceramic plugs in the
batteries.
3. When connecting and wiring batteries, use only insulated tools in order to prevent short
cuts. The battery terminals should be protected during transport.
4. The battery terminals and other lead components contain poisonous lead substances.
Please carefully wash your hands after handling batteries. Abandoned lead batteries are
toxic waste. They should be disposed of properly in designated collection points. Service
stations have facilities for receiving discarded starter batteries.
DO NOT POLLUTE NATURE BY DISCARDED BATTERIES!

6. You can get additional information about information related to batteries from these
sources:
- Finnish regulations of electrical safety (Sähköturvallisuusmääräykset), chapter 21
- Electrical card file (Sähkötietokortisto) cards No. TK 14.850, 14.855
- Security instruction for fork trucks by insurance company Teollisuusvakuutus
- specifications for telecommunication networks
30. Inspect or have inspected the Access Platform once a year (12 months) or more often
in adverse conditions. This so-called annual inspection should be carried out by a person
with a lifting device inspector qualification. The inspection should be registered to a dated
journal, which should always be kept in the Access Platform, for instance in the tool box,
and the owner of the equipment should keep a backup copy in a safe place. An officially
approved copy of the journal form is enclosed with the User's manual. Perform or have
performed the next inspection within 12 months after the previous inspection, and similarly
thereafter, during the same month in which the first factory inspection was performed. The
inspection should be renewed sooner if the Access Platform is used in demanding
conditions, if the supporting structures have been welded, or if there is any other special
reason to carry out a new inspection. A new inspection should be carried out in order to
secure the structure and general safety condition of the lifting equipment, particularly
regarding to any alterations affecting security issues. As to any changes or repairs, their
date, location in the equipment and the identity of the person who carried out the work
should be recorded in the journal. Please keep yourself informed about any changes of
official regulations since the last inspection. Any changes should be taken into account in
the new inspection. The manufacturer or an authorized dealer should be consulted prior to
any repairs or alterations of supporting structures.
31. Drive the Access Platform to a safe place before leaving it. Drive the boom and the
outriggers to transport position, switch off the engine and the main power switch. Keep all
keys in a safe place. Note! Keep all keys in one bundle, also when using the platform.
32. Never operate or drive the Access Platform under the influence of alcohol or narcotics.

CHECKING THE OUTRIGGERS
Check the functioning of the outrigger safety limits by extending the outriggers to the
supporting position (wheels are off the ground). In this position, the boom can be operated.
The outriggers have ground and position sensors; therefore a force of at least 6 kg (13,2
lbs) must be applied on the outriggers. The outriggers must be turned from the transport
position at least 75° towards the ground because of the functioning of the position sensor.
Checking the operation of the ground sensor once a week. The alarm signal should sound
if one of the outriggers is disengaged because of the quality of the ground or an uneven
set up.
- Set the Access Platform up in the supported position with wheels approx. 100 mm
off the ground.
- Lift one outrigger slightly off the ground.
- Try to lift the boom. The boom must not rise, if the Access Platform is not correctly
supported.
- Ask another person to raise the outrigger manually or using for instance a piece of
wood. Then lift the boom slightly off the transport support.
- Ask him to release the outrigger. The alarm should now sound and the upward
movements of the boom should be prevented. The alarm sound stops when the outrigger
is lowered back on the ground.
- Repeat the same for all outriggers.
If one outrigger or all of them does not work properly or if the alarm does not sound, the
Access Platform must not be used before the fault has been repaired.
When the sole of one or more outriggers is off the ground and the power is switched on
and the pedal is pressed, the alarm sounds. This does not prevent the use of the Access
Platform.
CHECKING THE TELESCOPE
Support the Access Platform on the outriggers so that the wheels are about 100 mm off
the ground.
The platform must be empty during this test.
Extend the jib to an angle of 45º with respect to the boom according to the markings at the
end of the jib and the boom, see fig. on page 18, item C. Lift the boom off the transport
support and turn the boom about 10 degrees to the left. Lower the boom completely.
Switch off the combustion engine by turning the ignition switch in the platform to OFF.
Move the ignition key to the control box of the turntable. Start the engine.
While being in the lower control position, lift the boom to horizontal position, see fig. on
page 18, item D.
Extend the telescope boom continuously until the load control stops the extension
movement.

Check that the triangular fastening item on top on the boom is straight; visually check that
the chains are tight. Note! If the triangular link is askew, in others words if one of the
chains is shorter, check the condition, fastening and adjustment of the chains. The Access
Platform must not be used, if for instance one of the chains is broken or its fastening or
adjustment is loose.

The telescope boom should stop when the middle painted mark is visible. The limiter of the
lifting radius of the telescope boom has now been checked.
Note! If the last section of the painted marking is further than 100 mm from the exit of the
boom, the Access Platform should not be used. Have the load control checked.
