MAINTENANCE SCHEDULES
5.1. GENERAL INFORMATION
5.1.1. INTRODUCTION
The TA50RT has been specially designed to reduce maintenance to a minimum. It is essential that the specified
servicing instructions are followed to ensure safety and reliability.
The hydraulic pump, motor, cylinders and pressure valves are self-lubrication internally. The turntable slewing
ring is grease packed and the corrosion-resistant pivot pins and bearings are pre-lubricated and require atten-
tion only at six monthly intervals.
Note:- During the guarantee period, minor oil leaks may occur until the various hydraulic components and
pipe fittings are bedded-in”. During the first three months of operational use, all hydraulic components, hoses
and pipe fittings must be inspected weekly for oil leaks etc. Corrective action should be taken as required.
5.1.2. HYDRAULIC OILS
The following table lists the recommended equivalent hydraulic oils for a TA50RT machine:
SHELL SHELL TELLUS T32
MOBIL DTE 13M
TEXACO RANDO HDZ 32
CASTROL HYSPIN AWH 32
ESSO UNIVISE N32
If a lubricant not listed in the table is to be used, the oil must comply with the following requirements:-
(a) Highly refined mineral oil incorporating anti-oxidant, anti-dust, anti-foam, and anti-wear additives.
(b) The oil must have good demulsibility, so that water is not circulated in the system.
(c) The optimum viscosity range at operating temperature is 16/40 centi Stokes.
(d) The viscosity index should preferably be 100, and not less than 90.
