Safety instructions

To reduce the risk of serious injury or death to yourself or others, carefully read
through this instruction booklet before putting the stoper to use. Always follow the
instructions given in this manual.

h Always wear a safety helmet, impact resistant eye protection with side protection

and ear protectors during drilling. Any local regulations that exist must also be
observed.

h When drilling in certain minerals, there is a risk of spark generation. Before

starting work, check that the machine is approved (in accordance with local
regulations) for work under such conditions.

h Always take great care when using the machine. The drill steel is subjected to

heavy loading and can break, with a risk of injury to personnel.

h Check that the hoses used are of the right quality, and that all hose connections

are in good condition and properly tightened.

h Before starting work on any of the systems, make sure that the air and water

systems are without pressure.

h Make sure that there are no concealed wires or other sources of electricity. Never

drill near any electric wires or other sources of electricity.

h Exposure to crystalline silica (sometimes called 'silica dust') as a result of drilling

in rock may cause silicosis, cancer or death. Never operate the stoper without
water flushing.

h A compressed air hose that comes loose can lash around and cause personal

injury or death. Check that the compressed air conections are not damaged and
that they are properly attached.

Operation

Using the stoper for the first time

When the stoper arrives from the factory, the inside of the machine is coated with
heavy oil to prevent corrosion.

After unpacking and installing the machine, pour a small amount of lubrication
oil into the air connection and operate the machine on partial throttle to clean the
interior. Follow this immediately with a liberal amount of air tool oil.

The stoper is lubricated with oil mixed with compressed air, which is taken to the
parts that need continuous lubrication. Oil is metered into the compressed air using
the FY500 lubricator connected to the air line.

Preparations before starting

1. Check the drilling equipment

h Check that all of the drilling equipment is in good working order.

h Check that the impact surface of the drill steel shank is flat with no signs of wear.

h Make sure that the air inlet and exhaust ports are free from obstructions.

h Check that the flushing holes in the drill steel and drill bit are not blocked and

that the flushing air/water flows through without obstruction.

h Ensure that the fittings are tight and leak-proof.

WARNING

A compressed air hose that comes loose can lash around and cause personal injury or
death. Check that the compressed air conections are not damaged and that they are
properly attached.

2. Blow out the air hose

Every day before using the drill, blow out the air hose to clear it from accumulated
dirt and moisture.

3. Check the lubrication oil level

h Fill the lubricator with oil if necessary.

h Always use a recommended lubricant.

Lubricant recommendation

Use a mineral-based air tool oil
