SECTION 1 PRONAR GO800 1.6 ENVIRONMENTAL RISK A hydraulic oil leak constitutes a direct threat to the natural environment owing to its limited biodegradability. While carrying out maintenance and repair work which involves the risk of an oil leak, this work should take place on an oil resistant floor or surface. In the event of oil leaking into the environment, first of all contain the source of the leak, and then collect the leaked oil using available means.
PRONAR GO800 SECTION 2 2.1 BASIC SAFETY RULES 2.1.1 MACHINE USE • Before use, the user must carefully read this Operator Manual and the WARRANTY BOOK. When operating the machine, follow all instructions in these documents. • The machine may only be used and operated by persons qualified to drive agricultural tractors and carrier vehicles and trained in the use of the machine.
SECTION 2 PRONAR GO800 reduce the level of noise during work, the operator cab windows and door should be closed. 2.1.2 HITCHING AND UNHITCHING THE MACHINE • Do NOT connect the machine to a multifunction arm of other type than the recommended by the manufacturer.
PRONAR GO800 SECTION 2 • When connecting the hydraulic lines to the hydraulic motor, make sure that the hydraulic system of the multifunction arm is not under pressure. If necessary, reduce residual pressure in the system. • In the event of injuries being caused by pressurised hydraulic oil, contact a doctor immediately.
SECTION 2 PRONAR GO800 • Do not transport the ditch digger in the working position. • The ditch digger may not be used or transported in conditions of limited visibility. • Do NOT ride on the machine or transport any materials on it.
PRONAR GO800 SECTION 2 cleaned and disinfected. In the event of more serious injuries, seek a doctor's advice. • Repair, maintenance and cleaning work should be carried out with the tractor/carrier vehicle engine turned off and the ignition key removed. Immobilise the tractor/carrier vehicle with parking brake.
• When driving with a raised ditch digger, keep a safe distance from electric lines. 2.2 RESIDUAL RISK Pronar Sp. z o. o. in Narew has made every effort to eliminate the risk of accidents. There is, however, a certain residual risk, which could lead to an accident, and this is connected mainly with the actions described below: •...
If any are destroyed or damaged, they must be replaced with new. Safety decals are available from your PRONAR dealer or directly from PRONAR customer service. New assemblies, changed during repair, must be labelled once again with the appropriate safety signs.

PRONAR GO800 SECTION 3 The ditch digger consists of the body (1) (FIGURE 3.2) with a connection (7) allowing coupling the ditch digger with the head of the multifunction arm. The ditch digger saw is driven by hydraulic motor (8) that is supplied through hydraulic lines (9) running from the multifunction arm.
PRONAR GO800 SECTION 4 4.1 GET READY FOR OPERATION The manufacturer guarantees that the machine is fully operational and has been checked according to quality control procedures and is ready for use. This does not release the user from an obligation to check the machine's condition after delivery and before first use. The machine is delivered to the user completely assembled.
