Instructions for safe operation
It is strictly forbidden to be inside of the risk zone of the grapple saw or crane.
Extraordinary caution should be taken when working near electrical lines or other sensitive
areas. Keep the safety distances. Expect risk of unforeseen movements. Any local
guidelines and regulations for working near power lines must always be followed. Var
ytterst försiktig när du kopplar gripsågen till och från kranen eller maskinen.
The operator must always have a clear oversight of the work area.
Never insert your hand or any other body part into the machine assembly or under hanging
load during work or when the hydraulic system is active (pressurized).
Walking under a hanging load is always forbidden and the operator is not allowed to lift a
load over people in any circumstances.
Localize any problem before any mending attempts, this will prevent unnecessary work and
possibly worsening the situation.
The grapple saws hydraulic hoses and pipes must always be kept in good condition.
Replace any of these immediately when any weakening is detected, especially the ones
connected to the grapple claws. Inspections are to be done daily. Air in the hydraulic
system can cause unforeseen movements, so always “bleed” the system by driving the
cylinder end-to-end several times after replacing any part of the hydraulic circuit.
Use original parts, by using original parts will ensure a more problem free use of the
product. Also note that if a failure is a result of not using original parts, the user assumes all
risk.
Never let an outside person handle the grapple saw / machine, before you make sure that
this person has understood all operating and safety instructions.
Always use appropriate safety gear, like helmet, safety goggles etc.
The cylinder for the grapple claws is equipped with a load holding valve."
"
Leave the holding valve installed, when the grapple saw will be used for taking down
trees in pieces. (knuckle boom cranes, truck cranes, tele-handlers or similar)."
The valve prevents the the grapple from opening (and dropping the load) in case of a hose
break."
Uninstall the valve, if the grapple saw will be used to fell whole trees that will be cut at
ground level. (Forestry harvesters, forwarders, excavators or similar).

Installation
Recommendations and tips
There are some recommendations and tips to consider when installing the grapple saw.
The grapple saw can perform slightly different depending on the machine which it is mounted on.
Both the SG220 and SG280 grapple saw work very well on trucks with long cranes. The SG220
and SG280 with radio control are popular, because no power cable needs be installed along the
crane boom. Only 2 hydraulic lines are needed (grapple open & Grapple close)

NOTE! Load holding valve on the grapple cylinder:!
Leave the valve installed, when the grapple saw is installed on a machine meant for
taking down a tree in smaller pieces. (Mobile cranes, tele handlers, knuckle boom
cranes or similar)
Uninstall the valve, if the grapple saw will be used to fell whole trees that will be
cut at ground level. (Forestry harvesters, forwarders, excavators or similar).
The machine must always be shut down when servicein or doing maintenance
work on the grapple saw!
SG220 and SG280 are to be mounted free hanging, with a rotator and link.
Fixed mounting is not allowed.
We recommend a minimum of ½” hydraulic lines along the boom. !
If quick connectors are used for the hydraulic lines, use one size bigger connectors in "
comparison to the hose size."
NOTE! No bleed line (from saw motor) needed..
If the hydraulic hoses are too small the saw will feel slow and counter (back) pressure will rise. "
The counter pressure should not exceed 50 bar (725 PSIs).
SG220 and SG280 can be installed on a variety; !
Trucks, forwarders, excavators etc.
These recommendations should be noted especially when installing the grapple saw on
a crane with a long boom. For example on a crane with a reach of 20-35 m (60 -120 ft), eg.
knuckle boom cranes, telehandlers or similar.
When installing on shorter cranes smal smaller lines will probably suffice.
The recommended oil flow for SG220 is approx. 50-80 l/min. (13 - 20 gpm).!
The recommended oil flow for SG280 is approx. 60-100 l/min. (15-26 gpm).!
The grapple saw will also work with less oil flow (eg. 40l/min.[10gpm]), but the saw will
then work slower.
Note! No bleed line (from saw motor) needed.
NOTE!
All machines are different.!
Different machines have different hydraulic pressure and flow.
Please contact the dealer or manufacturer for more information.

Open-center valve for grapple function.!
For the chain lubrication pump to work as supposed, the pressure must be relieved from
the hydraulic circuit for the grapple function. This may be achieved by using a “open-
center” valve (on the cranes valve set), meaning that oil can freely flow in or out when no
function is activated. Relieveing pressure will allow the pump to reset and fill with
lubrication oil and again administer it when the saw function is initiated next time.
Keep Grapple close function initiated while using tilt up, tilt down or saw
functions. This produces oil pressure to the grapple saw. Tilt up and tilt down
functions will also work with keeping grapple open function activated.

(6 bolts)."
"
Use rotator and link."
"
If a rotator with axle is used.
An adapter flange needs to be used "
between the rotator and the
grapple saw."
"
NOTE!!
Recommendation: use!
1/2” hoses to the grapple saw, to
ensure enough oil flow to the
grapple saw. (approx 50-80 l/min.).!
This may apply especially when the
unit is installed on a machine with a
long boom. (eg. a truck crane, !
knuckle boom crane).
It also helps to install 1/2” hoses
close to the tip of the crane slangar på sista ändan av
kranen.
Eg. if the crane has a JIB, the JIB
can have bigger hoses.
!
!
The grapple saw will also work with less oil flow but the saw will run slower.
If fast connectors are used on the hydraulic hoses, use one dimension bigger connectors in
comparison to the hoses, as fast connectors often restrict oil flow significantly."

Rotator
Grapple saw
Rotator"
SG220 or SG280 with radio control:
To allow free endless) rotation for the grapple saw "
you need a rotator with the option of channeling the "
oil for grapple open / close through the axle of the"
rotator.
In other cases the hydraulic lines can be installed to
bypass the rotator."
"
"
"
"
SG220 or SG280 with cable control:!
Use a hydraulic hose to shield the control
cable. Hose size approx. 1/2”-3/4”.
Preferably bundle the grapples open and
close hydraulic hoses togehter with the
shield-hose for the control cable,"
bypassing the rotator.
Note!!
Make sure the channels through the rotator
are big enoug to ensure the needed oil flow
to the grapple saw. !
!
The fittings for the grapple functions may also be
connected from the bottom of the rotator (depending
on the rotator model).

SG220 or SG280 with cable control:
Install the control cable to the cabin.
Make a junction for the cable on one or several points along the boom.
This can be done in many ways depending on what kind of base machine the grapple saw is
installed on.
This is to prevent the need to change the whole cable if a break were to occur.

Take in use - handheld remote (RC-T)
NOTE! Read page 27 (inspection before use) before using the product.
Charging the battery:
The delivery contains two batteries and on 110-240 V battery charger for the grapple saw.
If you wish to charge the batteries in the machine (12V or 24V) an inverter needs to be used.
The batteries are LiFePO4 batteriesr and need a smart-charger to be charged.
Ask your dealer for more information.
When the battery is empty, disconnect it to prevent damages to the battery. (The battery will
usually get empty very suddenly).
For example, even if it’s the end of your work day when the battery runs out, do not leave it
connected. As the grapple saw’s electrical system still is active and could deep-discharge the
battery. Deep-discharging a LiFePo4 battery may destroy the cells indefinitely.

2. Tilt down
3. Saw
Grapple open / close functions are
activated via the cranes integrated controls.
Keep the grapples close function activated while using the
grapple saws functions. This produces hydraulic pressure to
the circuit.
Controlling the grapple saw by remote safely:
SG220 RC-T and SG280 RC-T is controlled only by the remote.
No additional control box is to be installed.
Example:
Install a small plate to the side of the canes remote, where the grapple saw’s remote can be
placed. The grapple open / close functions are controlled by the original control for the crane.

NOTE! Read page 27 (inspection before use) before using the product.
Charging the battery:
The shipment includes two batteries and on 110-240V charger for the remote.
If one wishes to charge the battery from a 12V or 24V system the charger needs to be
connected to an appropriate inverter.
The batteries are based on LiFePo4 technology and always need to be charged with a smart
charger meant for LiFePo4 batteries with an appropriate Ampere feed.
Ask your dealer or the manufacturer for more information.
When the battery runs out disconnect the the battery to prevent any damages to the battery.
The battery will run out very abruptly, as it’s electronically controlled by a circuit that will
disconnect the load when charge gets too low.
For example, even if it’s the end of your work day when the battery runs out, do not leave it
connected. As the grapple saw’s electrical system still is active and could deep-discharge the
battery. Deep-discharging a LiFePo4 battery may destroy the cells indefinitely.
