This manual gives a technician a structured framework for every stage of the Simba 1254’s service life. The maintenance table alone is a complete planning tool – it maps each task to a specific interval, whether calendar-based or tied to diesel engine hours, so nothing gets skipped and no component runs past its service window. Beyond the schedule, the manual dives deep into the systems that define this drill rig: the Feeder 200-series with its cradle, slide pieces, and feed cylinder; the Rod Handling System with its carousel, gripper arms, and indexing adjustments; the hydraulic system with its pump settings, pressure regulators, and oil sampling routine; and the Deutz diesel engine with its fuel, air, oil, and belt maintenance. Brake system testing, power train oil changes, reeling unit upkeep, and the automatic central lubrication system all get dedicated chapters with step-by-step procedures, exploded illustrations, and the exact pressure or torque values a technician needs to work confidently.

Why This Manual Matters

Epiroc designed the Simba 1254 for production drilling, and the maintenance procedures in this document are what keep the machine in that role rather than parked for repairs. The hydraulic system alone relies on dozens of specific pressure settings – from the 200-220 bar percussion and positioning pressure down to the 16-20 bar stand-by pressure on the main pump, the 120 bar rotation pump setting, and the 30 bar back-pressure valve for drill rod support. Miss those numbers and you risk damaging the rock drill, the rod handling system, or the feed unit. The brake system chapter similarly calls for a service brake pressure of 80-85 bar, a parking brake pressure of 25 bar, and an accumulator charge pressure of at least 35 bar – all factory-set values that must be verified with a pressure gauge, not guessed. This Epiroc Simba 1254 maintenance manual puts those numbers in front of you before you open a valve or turn a screw.

The feed unit and rod handling system sections are equally critical for machine uptime. The manual explains how to adjust the cradle on the feed beam, replace worn slide pieces and slide rails, set the drill rod support pressure, and tune the RHS indexing cylinder stroke length. It also covers the less obvious maintenance work – lubricating the feeder grease nipples, checking the carousel indexing friction clutch, inspecting the reeling unit collector for carbon brush condition, and draining water condensation from the fuel tank. These are the tasks that separate a machine that runs reliably from one that suffers repeat failures.

Who This Manual Is For

This PDF is written for maintenance personnel, service technicians, and operators who are responsible for the upkeep of an Epiroc Simba 1254. The manual assumes basic familiarity with mining equipment and hydraulic systems, so it does not stop to explain what a pressure gauge or a torque wrench is – it goes straight to the procedure, the specification, and the safety precaution. If you are new to the machine, the component locations chapter and the system overview illustrations give you a solid starting point for understanding how the major assemblies relate to each other. If you have been working on drill rigs for years, the maintenance table and the detailed pressure settings are what you will reach for most often.
