DESCRIPTION
The JLG K13 is of the parallel linkage vertical boom design, mounted on a road
towable trailer. The unique yet very simple boom configuration gives the maximum
safety and controllability combined with a robust construction to withstand a heavy
working environment.
The K13 machine is designed for two-man capacity (200 kg S.W.L.)
The machine incorporates a bottom boom with tie rod, a short vertical boom and a top
boom with tie rod. The K13 also has an independent hydraulically operated flick-out
boom for extra manoeuvrability.
The hydraulic system is of a failsafe design throughout, with built in hydraulic lock
valves on all the rams as a precaution against hose failure. The machine is controlled
by means of proportional manual control valves of the direct hand lever operation
type.
Emergency lower valves are fitted as standard to allow the machines to be lowered
from either the platform or the base. There is also a base control valve fitted as
standard, repeating all the functions of the basket control valve.
The outriggers are fitted with interlocks, to prevent the booms being raised without
the outriggers being extended. A simple system of warning lights show the power is
on and each of the outriggers is under load.
The K13 meets or exceeds the applicable requirements of AS1418.10 as originally
manufactured for the intended applications and use.

WARNING NOTICES
1. DO NOT operate the machine unless you have been fully trained in the safe
use of the machine.
2. DO NOT operate the machine on soft, slippery or sloping ground unless
adequate precautions have been taken.
The stabilisers are designed to operate on firm and level ground with a
minimum bearing strength of 31 N/cm  .The maximum load imposed by an
outrigger is 10.3 kN.
Advice should be obtained from JLG as to the type of supports and
precautions required before attempting to operate the machine outside these
parameters.
3. DO NOT operate the machine unless all four stabilisers are down in full
contact with the ground, the machine is level and the wheels are lifted clear of
the ground.
4. DO NOT use any equipment in the basket to increase the reach or working
height of the machine, e.g. ladders.
5. DO NOT fit any additional equipment to the machine which would increase
the wind loadings, e.g. notice boards.
6. DO NOT use the machine for any application which may produce special
loads or forces; JLG should be consulted for approval giving full details of the
application prior to use.
7. DO NOT use the machine close to live electrical conductors. This machine is
not insulated and does not provide protection from contact or proximity to
electrical current.
If you are working in an area with overhead power lines, contact your local
authorities to find out the minimum safe approach distances applicable to your
job site. A site-specific risk assessment must be carried out and risk control
measures put in place before work commences. A dedicated observer may be
required along with other risk control measures. Consult AS2550.1 and your
local authorities for details.
