2. General safety instructions
Read all the instructions before using the machine.
Know your power tool - Read the instruction manual carefully. Get to
know your own skills and limitations as well as the potential hazardous
characteristics to this tool.
DANGER! - The use of any accessories or attachments other than the ones
recommended in these operating instructions or the T-DRILL catalogue may
lead to a risk of personal injury.
NOTE! Never detach the power unit from the
T-DRILL tee forming unit. Detaching the power unit will damage the
alignment produced in factory.
NOTE! - The T-DRILL T-35 is designed for use with power unit T-DRILL has
chosen. Using any other power units with the T-DRILL T-35 tee forming
unit is not permitted.
IMPORTANT! The warranty is void if the power unit is
detached from the tee forming unit!
2.1 Work area
a) Keep the working area clean and well lit.Cluttered or dark
areas and invite injuries.
b) Do not operate power tools in explosive atmospheres,
suchs as in the presence of flammable liquids, gases
and dust. Power tools create sparks which may ignite the dust or
fumes.
c) Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
2.2 Electrical safety
a) Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs

with earthed (grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces,
such as pipes, radiators, ranges and refigerators. There
is an increased risk of electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. Keep cord away
from heat , oil, sharp edges or moving parts. Damaged
or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of cord
suitable for outdoor use reduces the risk of electric shock.
2.3 Personal safety
a) Stay alert, watch what you are doing and use common
sense when operating a power tools. Do not use a
power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of in attention
while operating power tolls may result in serious personal injury.
b) Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used dor appropriate
conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in
the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energising
power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewellery or long hair can
be caught in moving parts.
g) If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection can
reduce dust-related hazards
2.4 Power tool use and care
a) Do not force the power tool. Use the correct power tool
for your application. The correct power tool will do the job
better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it
on and off. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
c) Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool or
these instructions to operate the power tool. Power tools
are dangerous in the hands of untrained users.
d) Disconnect the plug from the power source from the
power tool before making any adjustments, changing
accessories, or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool accidentally.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly maintained
power tools.

INSTRUCTION MANUAL

f) Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind and
are easier to control.
g) Use the power tool, accessories and tool bits etc. in
accordance with these instructions and in the manner
intended for the particular type of power tool, taking
into account the working conditions and the work to be
performed. Use of the power tool for the operations different
from those intended could result in a hazardous situation.
2.5 Service
Repairs must be carried out by an authorised T-DRILL service
agent – This electric tool complies with the relevant safety requirements.
Repairs should be carried out only by certified persons using original spare
parts; otherwise, this may result in considerable danger to the user.
2.6 Safety instructions for tee forming
Do not touch the rotating tool when the work cycle is in
progress.
Mind your fingers. When fixing the machine to the tube, be careful not
to leave your fingers between the machine and the tube.
Use protective gloves. When handling the tools, be careful with the
cutting blades.
Use protective shoes. A falling machine or tool may damage your feet.
Use safety glasses. Also use a face or dust mask if the cutting operation
creates dust.
Use protective gloves. Lubricating oil may irritate the skin.
Pay attention to adequate ventilation. The fumes emitted by the
lubricant may irritate your eyes and respiratory system.
Familiarise yourself with the contents of the safety data sheet
regarding the lubricants.
Provide adequate protection in order to prevent damage. Loose chips
are hot and sharp.

Never carry the tool with your finger on the trigger. Be careful
to avoid accidental starting of the machine when handling it.
Always use protective gloves when cleaning the collar. The edges of
the collar are sharp.
Keep your hands away from the danger area. Do not use
inadequate protective gloves as they may get caught in the rotating tool.
Never use the machine with the trigger lock on.
The vibration passed on to the operator’s hand is less than 2.5 m/s (8.2

3. T-DRILL T-35, general
3.1 Introduction
T-DRILL T-35 is a special tool designed for forming tees mechanically in
copper tubes typically found in domestic, commercial and industrial tubing
systems. The T-35 extrudes an outlet in the run tube and the branch tube can
be joined to the outlet by brazing.
Before using the T-35, make sure that you have read and fully understood
the safety instructions, which apply to all power tools and to the capabilities
of this special tool.
The T-DRILL T-35 includes an electric network-driven power unit with
accessories. The power unit is grounded 120 V or double insulated 110 V
or 230 V.

3.3 Information about Accessories
For easier use of T-DRILL T-35 the following accessories are available:
3.3.1 Notcher ND-54
The tube end notcher shapes the end of the branch pipe to match the inner
curve of the run tube. In this way maximum flow is achieved in the joint. The
notcher also presses two dimples simultaneously in the end of the branch
tube, one acting as a depth stop and the other for inspection of the joint
after brazing.
1. Notcher, 2. Gauge block, 3. Ring
3.3.2 Gauge block and ring
The correct size settings of the T-DRILL head for various tube sizes can
easily be checked with the gauge block. The size range is NS 1/4"-1" with
the gauge block and 1¼” with the ring.
3.3.3 Lubrication for copper
A bottle of lubricant to be used for forming the outlet in copper tube, is
included.

6.2.2 Fine adjustment of the outlet diameter
NOTE! Extend the forming pins before adjusting the outlet diameter.
To extend the forming pins (1) press
the conical cover (2) in the direction
of the shank. At the same time twist
the shank (3) clockwise until a
positive stop is reached, and the
forming pins extend. Make a location
mark on the cover and the conical
cover.
Each T-DRILL head is adjusted at the factory to correspond to the nominal
size stamped on the cover of each T-DRILL head. Changing the tube sizes or
the way of joining may require adjustment of the T-DRILL head in order to
