Practical guidance for safe operation, daily checks and machine care

Book a service

Before you start: safety first

Read the machine's operator manual before first use and make sure you have received certified training.
Wear protective equipment: helmet, safety boots, high-visibility vest and glasses where needed.
Always use three points of contact when climbing on or off – never jump down.
Fasten the seat belt before starting the engine and make sure the work area is clear of people.
Never carry passengers and never let anyone stand under raised parts.

Daily pre-start checks

Engine oil, coolant and hydraulic oil levels.
Air-filter condition and restriction indicator.
Oil or fuel leaks under and around the machine.
Lights, horn, reverse alarm and mirrors.
Drain water from the fuel water separator.
Track tension, rollers and track shoes.
Blade and ripper condition.

Operating tips

Push full loads over short distances – long pushes cut productivity.
Use slot or side-by-side dozing to reduce spillage.
Work up and down slopes, not across them.
Minimise track spinning on rock to reduce wear.

Working in Iraqi conditions

Clean radiators and coolers daily during summer and dust storms.
Let the engine idle 3–5 minutes before shutdown after heavy work.
Park in the shade during breaks and avoid long idling in direct sun.
Use clean fuel and only oils meeting approved SDLG specifications.

Periodic care schedule

Every 50 operating hours

Grease pivot points and pins.

Every 250 operating hours

Check belt tension and hose condition.
Check batteries and connections.

Every 500 operating hours
