5.1 Delivery and transport
Delivery
Check the woodturning lathe for vi ible tran port
damage immediately after delivery. If you notice any
damage on the woodturning lathe, plea e inform the
carrier or di tributor immediately.
5.2 Transport
The improper tran port of individual device and pack-
aged or unpackaged device that are tacked on top of
one another or next to one another un ecured, i liable to
cau e accident and damage or malfunction for which
we cannot a ume liability or provide any guarantee.
Tran port the cope of delivery ecured again t hifting
or tilting with a ufficiently dimen ioned indu trial truck to
the in tallation ite.
General risks during internal transport
Load may only be tran ported by authori ed and
qualified per on . Act re pon ibly during tran port and
alway con ider the con equence . Refrain from daring
and ri ky action .
Gradient and de cent (e.g. driveway , ramp and the
like) are particularly dangerou . If uch pa age are
unavoidable, pecial caution i required.
Before tarting the tran port check the tran port route for
po ible danger point , unevenne and di turbance
a well a for ufficient trength and load capacity.
Danger point , unevenne and di turbance point mu t
be in pected before tran port. The removal of danger
pot , unevenne , and di turbance by other
employee at the time of tran port pre ent a major ri k.
Careful planning of internal tran port i therefore e ential.
5.3 Packaging
All packaging material and packaging aid u ed for the
woodturning lathe are recyclable and mu t therefore
alway be recycled.
The delivery packaging i made of cardboard, o plea e
di po e carefully by having it chopped up and given to
the recycling collection.
The film are made of polyethylene (PE) and the
uphol tery part are made of poly tyrene (PS). Deliver
the e ub tance to a collection point for recyclable
material or to the wa te di po al company which look
after your region.
5.4 Storage
The woodturning lathe mu t be cleaned thoroughly prior
to torage in a clean, dry, fro t-free environment. Cover
the machine with a protective tarpaulin.
Ambient temperature range: –25 °C to +55 °C.
CAUTION!
Ri k of injury from device falling over or falling from
a forklift, pallet truck or tran port vehicle.
Only u e tran port device and load u pen ion gear
that can hold the total weight of the load.
CAUTION: DANGER OF TIPPING
The device may be lifted un ecured by a maximum
of 2cm.
Employee mu t remain out ide the danger zone
and out of range of the load.
Warn employee and advi e them of the hazard.
