4.5. Working parts
Before operating the rake check tines’ condition.
Worn or damaged tines should be immediately replaced with new ones.
CAUTION:
During replacement of working parts, it should be used personal protective
gloves.
4.6. PTO shaft
Before operating, read bar manufacturer's manual placed on the bar. Follow all safety
precautions in that manual.
Use only PTO shafts recommended by rake’s manufacturer with guards in good condition.
Pay particular attention to PTO shaft’s guards and rake’s and tractor’s spline shaft guards.
Never work with damaged guards.
In order to operate safely use only fully technically fit, undamaged PTO shafts. Damaged PTO
shaft shall be repaired or replaced with new one.
Before operation, check all guards (in tractor, machine and the shaft), if they are in place and are
functional. Any worn or damaged guard must be replaced. Damaged or missing guard of drive
shaft may cause serious accident and even death.
Possible inclination of the shaft depends on shape and size of the guard. Before operation check
if guards in any position are not damaged or locked.
The shaft should be disconnected from the machine if steering angle is too much.
Before any operation make sure whether PTO rpm have proper rotational direction.
4.7. Hydraulic assembly
Caution! Hydraulic assembly is under pressure! Hydraulic oil under pressure may permeate
through skin and cause serious injury, therefore skin and eyes should be protected in particular.
In case of injuries caused by a liquid under pressure, call a doctor immediately.
Hydraulic hoses can be connected to tractor's hydraulics, provided that both the tractor’s and
the tedder's hydraulic assemblies are not under pressure. To remove the pressure from the hoses
just simply restart the tractor's hydraulic valves several times, once the tractor is off.
When dismounting the machine from the tractor, set the equipment aside, deflate the pressure
from hydraulics and turn tractor's engine off.
When controlling for hydraulic assembly's malfunction and looking for oil leaks, it is forbidden
to touch any potential leaks until the entire assembly is under pressure.
Note! It is recommended that the hydraulic oil used should not exceed 10 oil purity class
in accordance with NAS 1638.
When using hydraulic hoses:
Avoid stretching the hoses when operating.
Do not allow hydraulic hoses to get deflected.
