4. ASSEMBLY AND MOUNTING
Read these instructions before starting any assembly or mounting of crane. Improper
mounting, carried out in a manner other than specified in this manual, may cause
dangerous situations to user and surrounding objects. Improper mounting, useage and
installations will void the manufacturer warranty.
4.1 Mounting forest crane to Palms trailer
Mounting of forest crane should be performed at the dealer service center or by person
authorized by the manufacturer or dealer. Mounting/detaching the crane can also be
made by end user, if professional equipment is used, all safety regulations are followed
and at least one qualified mechanic is present during all the mounting/detaching process.
Strength class for mounting bolts of slewing device-support legs (pos. 1, fig.5) and
support legs-trailer (pos. 2, fig. 5) has to be 12.9 (DIN912). Use self-locking nuts M24.
The tightening torque for the mounting bolts of the crane (pos. 1, fig. 5) and supporting
legs (pos. 2, fig. 5) is 1220 Nm.
Retighten bolts after the test run and after first 8 hours of use! Check after
40 working hours, tighten if needed. Visual check is required prior every
working session.

V 1.03 EN 2012 Palmse Mehaanikakoda LLC 12
5. HYDRAULIC SYSTEM
5.1 Connection
Before connecting forest crane to the tractor’s hydraulic system, make sure, that
hydraulic oils are compatible. Forest crane has been tested and should use Addinol
HVLP 32 hydraulic oil or other compatible oil that meets DIN 51524-3 requirements.
Check level of hydraulic oil. We recommend connecting the pressure hose to the singleacting hydraulic outlet and the return hose to the tank via the return filter. Intended
minimum flow rate for filter is 70 l/min and the filtering density is 10-50 µm.
Make sure the connection has made properly.
In order to avoid valve damages, always connect hydraulic hoses
according to user manual!
Make sure you connect the return line, bolder hose, always first and
disconnect it last.
Ensure, that the control valve pressure line, thinner hose, P has been
connected properly and that the return line, bolder hose, T is not
obstructed.
In case there is obstruction in return line (quick couplings are not
connected or are not locked properly) the pressure might rise over 10 bar
and cause malfunction of control valve.
Forest crane can be also connected to the double-acting hydraulics outlet.
If this option will be used, make sure, that the lever of the double-acting
valve is in the right position and the pressure is directed to the pressure
connection of the crane’s control valve. Check also vehicle’s operating
manual for hydraulic system connecting instructions.
If your crane has pilot operated valve control with pilot operated TP return
line installed, TP return line has to be connected straight to the hydraulic
oil tank. Pilot operated TP line hose has 1/4” size connection fitting. Some
vehicles have separate quickcoupling installed on hydraulic oil tank,
which you can use for pilot operated TP line, some of them do not.
Pilot operated TP return line can not take more than 6 bar of backpressure!
Page 15
FOREST CRANE PALMS 840
V 1.03 EN 2012 Palmse Mehaanikakoda LLC 13
Do not connect pilot operated color TP line in to the main return line!
If crane is not used, leave pilot operated TP return line open. Do not close
TP return line with regular plug fitting. Pressure can build up and damage
valves.

6. OPERATING INSTRUCTIONS
6.1 Testing
Ensure that the control valve levers are in the middle position. Swich on the pump and let
oil flow through the valve for a while. Lower the support legs.
Ensure that there are no people or obstacles in the operating area. The
danger zone is 20 m!
Carefully drive crane movements one by one in the way, that all cylinders reach their
extreme positions and repeat this until all movements are smooth.
Be careful when getting air out of system. If you drive cylinder to its extreme
position at full force, the air pressure in the cylinder will damage the seals!
Be extremely careful, when there is air in the cylinders!
After testing forest crane, inspect connections and repair leaks if any appeared. Check the
mounting bolts of the crane and support leg, tighten them if necessary. Check the hydraulic
oil level, and fill up if necessary.
6.2 Practice runs
Forest crane should not be operated if temperature is below -25C. Note that
the hydraulic seals, hoses and steel structures may get damaged at low
temperature. When starting to work at cold temperature, first let the oil flow
freely through the valve for a couple of minutes. The maximum operating
temperature for hydraulic oil is +75C.
Drive through every movement with an unloaded crane, paying attention to the positions in
which the crane might hit surrounding obstacles.
Never move the boom to its extreme position at full speed!
Move the control levers smoothly and stoutly, avoiding quick and jerky movements.
Learn to use several functions simultaneously. Start at low engine speed to avoid sudden
movements. After you have become accustomed to the crane’s movements, choose
appropriate engine speed so, operations are smooth and efficient, but you still have the
movements under control. Loading big and heavy logs from distance, keep load close to
the ground. When reaching the trailer, lift it up to load. When unloading do vice versa.
Page 25
FOREST CRANE PALMS 840
V 1.03 EN 2012 Palmse Mehaanikakoda LLC 23
Working on inclined surface, do not operate with the full lifting torque and be extremely
careful. Loading uphill note, that turning crane with too much load might cause the oil
pressure in slewing device cylinders to reach critical point, where shock valve has to
intervene. This could make slewing device uncontrollable and crane might turn back to
downhill direction in a way, that it might fall over. In such case lower the load as close to
ground as possible, but not too rapidly .
Use the support legs only for purpose to provide additional support for the
vehicle! Don’t forget to lift the support legs UP before moving to another
place!
Support legs are equipped with extra valves, wich will keep them in working position in
case feeding hoses of support leg cylinder breakes.
Do not exceed the speed limit when driving! Adjust speed according to the
road and weather conditions. Be especially careful on turns! For driving
always attach crane by grapple to trailers frame. When driving with load,
leave one log sticking out from pile and attach crane by grapple to it. Keep
crane boom as low as possible.
Do not use support legs in DOWN position while parking!
When using forest crane in combination with forest trailer, use trailer parking leg (fig.8) and
make shure, that crane support legs are not leaning to the ground.
Figure 16. Parking leg of trailer
Page 26
FOREST CRANE PALMS 840
V 1.03 EN 2012 Palmse Mehaanikakoda LLC 24
7. DETACHING FOREST CRANE
Choose sufficiently hard and even level ground for detaching forest crane. Ensure, that no
unauthorized persons are around crane during detaching and storing process. When
storing control valve, make sure it is out of the reach of children.
Lower the support legs to support crane properly.
Fix crane firmly by proper hoist.
Make sure that crane can not lean or fall over.
Detach quick couplings and put covers on them.
Always switch the pump off before disconnecting quick couplings!
Detach crane from the vehicle.
8. STORAGE INSTRUCTIONS
Clean forest crane and if necessary, repaint any points, where paint has peeled off or
gets damaged, this will avoid rust.
Lubricate forest crane thoroughly (see lubricating instructions).
Do not leave electric operated and pilot operated valve controls uncovered, water and
moist may damage wiring and contacts.
Release pressure from the cylinders.
Protect the cylinder piston rods and exposed parts of the control valve with grease.
Store forest crane in a sheltered area (under the roof), avoid direct contact with the
ground.
