Dynapac's medium heavy vibratory soil compactor is the CA 250. This compactor is available in (smooth drum), P (padfoot) and PD versions respectively. Both the P and PD versions are used mainly on cohesive material and disintegrated rock. All types of base courses and subbase courses can be compacted deeper and the interchangeable drums, ie, std to P, D to PD and vice versa, facilitate even greater variety in the range of application. The cab and safety-related accessories are described in this manual. Other accessories, such as compaction meter, speed recorder and CCS/RA field computer, are described in separate instructions.

SPECIAL INSTRUCTIONS
Standard oils and other recommended fluids
Upon delivery from the factory, the various systems and components are filled with the oils specified see lubricant specification and they can be used at ambient temperatures from -10C to +40C (14F - 104F). A maximum temperature of +35C (95F) applies for biological hydraulic fluid.
When operating in hotter ambient temperatures, but up to max. +50C (122F), the following instructions apply: The diesel engine can handle this temperature with the standard oil, but the following oils must be used in the other components: Hydraulic system with mineral fluid: Shell Tellus TX100 or corresponding. Other components using transmission oil: Shell Spirax HD 85W/140 or corresponding.
Temperature
The temperature limits apply to standard versions of the roller. Rollers that are fitted with additional equipment, such as noise suppression, etc., may require extra observation in the higher temperature ranges.
High-pressure washing
When washing the machine, do not direct the jet of water directly at the fuel or hydraulic fluid tank covers. This is particularly important when using a high-pressure washing unit. Do not spray water directly on electric components or the instrument panel. Put a plastic bag over the filler cap of the fuel tank and secure with a rubber band. This will prevent water from entering the venting hole in the filler cap. This could otherwise cause operational disturbance, for example, a clogged filter.
Fire fighting
In the event of fire in the machine, use an ABE-powder fire extinguisher if possible. A BE type carbon dioxide fire extinguisher may also be used. If the roller is equipped with a protective structure (ROPS, Roll Over Protective Structure), or protective cab, never subject the structure or cab to welding or drilling. Never attempt to repair a damaged structure or cab; they must be replaced with new ones. When using an auxiliary battery to assist starting, always connect the positive terminal of the auxiliary battery to the positive terminal of the roller battery, and negative to negative.
