Product description Operating instructions

1.1.2 Intended purpose

The Chain saw HCH5011 is designed and built for the following
application:

• Cutting of concrete (including reinforced), masonry and natural stone

• Cutting of severance cuts, flush cuts and cross-cuts in ceilings, floors
and walls

• Only original TYROLIT Hydrostress AG tools (chains) should be used

The information provided in Chapter 1 “Technical Data” 1.2,  1-4
represents the mandatory usage limits and rated data

1.1.2.1 Safety measures

Any use other than for the intended purpose (see Chapter 1.1.2,  1-2)
constitutes improper use or misuse.

Since improper use or misuse can sometimes results in considerable
danger, here details of what we believe constitutes improper use or
misuse.

The following applications are prohibited:

• Cutting without the safety devices provided

• Cutting wood, glass and plastics

• Cutting without system and tool cooling

• Cutting in explosion-protected areas

• Cutting loose parts

• Incorrect or absence of waste water disposal (saw sludge)

1.1.3 Workplace and danger areas

Allow enough room for manoeuvre to ensure danger-free working.
Make sure you have sufficient lighting at your workplace.
Clearly cordon off the danger area so that no person can enter the danger

area during sawing.
The front, underneath and rear of the sawing area must be protected so

that persons or equipment cannot be harmed by falling parts or sawing
sludge, or by the protruding cutting tool.
Secure lumps of concrete that have been loosened against falling.

Breathing in the water fog that is created is a health hazard. Ensure
adequate ventilation in sealed-off areas.

The sludge resulting from cutting is very greasy. Remove this or ensure
that you or other people do not slip on it.

6.1 General

Before proceeding read Chapter 2 «Safety instructions»,  2-1 in these
Operating instructions. Be sure also to take note of all the danger
information given here and follow the instructions on how to avoid physical
injury and damage to property.

6.1.1 S afety instructions

It is essential to observe the following safety instructions, in particular in
relation to the operation of the HCH5011.

Danger

Danger of falling heavy parts.

When performing the types of work described in this chapter, it is
essential to wear the following individual protective equipment:
helmet, goggles, protective gloves and safety shoes. (s ee “Chapter
2” 2.3.7,  2-4)

It is essential that the work instructions and proc edures described
in this safety manual are followed.

Failure to observe this regulation may lead to serious physical
injury, and possibly even death, and to property damage.

Danger

Danger from machine suddenly starting up.

Before switching on the Chain saw HCH5011 the operator must
ensure that no other person is present in the danger areas.

Failure to adhere to this regulation may result in cut wounds to
body parts and damage to property.

Danger

When working with a worn chain there is a danger of the chain
breaking.

Worn chains must be replaced with new ones.

Failure to comply with this regulation may lead to serious physical
injury or death.

HCH5011 / 001 6-1

Operation Operating instructions

Danger

Working with an incorrectly fitted chain will reduce the lifetime of
the chain and there is a danger of the chain breaking.

Use the fitting aid (chain engraving) to correctly insert the chain.

Failure to comply with this regulation may lead to serious physical
injury or death.

Danger

Noise danger

When using the Chain saw HCH5011 hearing protection must be
worn.

If this instruction is not followed irreparable hearing damage may
result.

Danger

Danger from uncontrolled movements

When the Chain saw HCH5011 is switche d on , alwa y s ho ld it wi th
both hands using the handles. Thumb s and fingers must be closed
around the handles. Otherwise you may loose control o f the Chain
saw HCH5011. Handles must always be clean and dry.

Failure to observe this regulation may lead to serious physical
injury, and possibly even death, and to property damage.

Danger

Danger from working at excessive chain speed or wit h insufficient
water feed.

This can lead to excessive wear of the chain, which in turn can
result in loss of stability and the chain breaking.

Operate the Chain saw HCH5011 at the correct speed and with
sufficient water feed.
Do not exceed a hydraulic flow of 45 l / min and 140 bar. The
working pressure of the water should be a minimum of 2.5 bar and
