Robomow®- Safety Features
1. Child Guard / Safety Guard
This menu option offers a safety feature to help prevent children or others not familiar with the safe
operation of the mower to operate it freely.
2. Lift Sensor
There is a sensor located on the front caster wheel of the mower. In the event the front of the
mower is raised approximately 1-inch from its resting position on the ground during blade
operation, the blades will stop rotating immediately (< 1 second).
3. Sensor Equipped Bumpers
The front and rear bumpers are equipped with contacts that will activate when the mower strikes a
solid, fixed object when that object is at least 6-inches in vertical height from the supporting
surface of the mower. When the bumper sensor is activated, the mower will stop movement in that
direction and reverse itself away from the obstacle. In manual blade operation, bumper activation
will stop the rotation of the blades immediately (<1 second).
4. Emergency Stop Switch
Located on the top outer surface of the manual controller, red in color. Pressing this button at any
time during operation will stop all mower movement and stop the rotation of the blades
immediately (<1 second).
5. Automatic Mode Recognition
The Robomow is designed so that it cannot be operated in the manual mode while the Manual
Controller is in its pocket and it cannot operate in the automatic mode while the Manual Controller
is removed.
6. Two-Step Operator Presence Control
While in manual mode, it requires two independent finger actions in order to engage the mower
blades. Once engaged, the mower blade button must remain depressed to continue blade
operation. Once released, the two-step engagement process must be repeated.
7. Electronically Controlled Charging System
The Robomow is equipped with an on-board charge control system. This allows you to keep the
charger connected at all times, even after the battery is fully charged. The control system will
prevent an overcharge to the battery and keep it fully charged and maintained for the next use.
8. Sealed Power Pack
The power pack that operates the Robomow is completely sealed and will not leak any type of
fluids, regardless of position. In addition, the power pack contains a one-time-use fuse in the
event of a short-circuit or power malfunction.
9. Perimeter Switch and Perimeter Wire
The Robomow cannot operate without a perimeter wire installed and activated through the
Perimeter Switch. In the event the Perimeter Switch is turned off or otherwise fails to function, the
Robomow will stop operating. Likewise, should a break in the perimeter wire occur the Robomow
would again stop operation. A break in the perimeter wire prior to operation will prevent the
Robomow from operating. The Robomow can only operate within the boundary of the perimeter
wire.
10. Auto-Off Perimeter Switch
The auto-off feature of the perimeter switch shuts down the perimeter switch operation after
approximately 5 hours of continuous operation. This is typically 2 to 3 hours after which a fully
charged Power Pack will need to be re-charged. This helps to prevent unauthorized persons from
attempting to re-start the Robomow after it has completed its operation.

9
11. Over-Current Monitoring Protection
Each of the three blade motors and each of the two wheel drive motors are monitored
continuously during operation for any situation that may cause these motors to over-heat. In such
event, the Robomow will stop operation of at least that motor and possibly the mower itself and
indicate that the motor is cooling down. While unusual, this may happen when the mower is put in
grass that is severely overgrown; the underside of the mower is clogged from poor cleaning
maintenance; the mower has encountered an obstacle that is unable to activate the bumper
sensor preventing it from moving; or a problem landscape area has caused the mower to get stuck
and is preventing it from moving.
12. Automatic departure warning alert
When the mower is scheduled to depart the Docking Station automatically per a scheduled time, a
warning buzzer and the operating lamp will activate 5 minutes prior to departure. This is a warning
notification to clear and inspect the area.
This warning symbol will be found at several
points throughout the pages of this manual.
It is intended to highlight an important safety,
warning or cautionary message.
Please pay particular attention to these
areas and be sure you fully understand
the message before proceeding.

Docking Station & Perimeter Wire Setup
Figure 1.1 Docking Station Assembly
1.1 Docking Station Zone
Before setting up the perimeter wire and Docking Station, it is best to examine your lawn and determine
the best location for the Docking Station. The Docking Station is a fully automatic solution suitable for one
area or zone, thus it is recommended to set it up in the largest area or zone. To mow other areas, simply
drive the Robomow to the area you want to mow and operate it in the automatic mode as explained in this
Manual. When this area is completed, drive the mower back to the station for re-charging.
Setup in Docking Zone
1.2 Docking Station Placement
 There is a maximum distance of 50 feet (15 meters) from the receptacle to the Docking Station, see
figure 1.2. Do not use an extension cord to increase this distance. Should a distance of more than 50
feet (15 m) be required, refer to a locally qualified electrical professional to install a power source in
order to place power within the specified distance.
 Position the Docking Station with the fence facing to the inside of the lawn. See figure 1.2.
Figure 1.2 – Distance From Power Receptacle
CAUTION! Refer to the specific safety instructions related with operation of
the Robomow with a Docking Station, as specified in the Safety chapter.

13
Greater than
8 feet (2.5m)
Note: The power supply is suitable for outdoor use, yet it is required placing it in a sheltered place, dry
location, which is well ventilated and not exposed to direct sunlight. It is recommended to place the
Docking Station as close as possible to a receptacle, roll the extra cable and store it near the power
supply. See paragraph 1.15 for further details on the cable.
• Place the Docking Station at minimum distances from corners of the perimeter as shown in figure 1.3
• A minimum distance of 6 feet (2 meters) is required between the Docking Station fence and any
obstacle not excluded with the perimeter wire. See figure 1.3.
Figure 1.3 – Distance From Corners and Obstacles
• A minimum distance of 8 feet (2.5 meters) is required between the Docking Station fence and the
perimeter wire. See figure 1.4.
Figure 1.4 – Distance From Perimeter Wire
CAUTION! Serious Injury Can Occur! When placing the power
cord leading to the Docking Station insure it is fastened securely
to the ground and does not present a tripping hazard.
Do not cross over surfaces such as sidewalks and driveways
where it cannot be fastened securely.

• The Robomow is impervious to water and rain, however it is recommended to place the Docking
Station away from sprinkler heads for maximum protection. See figure 1.7
Figure 1.7 – Avoid Placement Near Water Sprinklers
Now, knowing the location of the Docking Station, you can begin to setup the Perimeter Wire in the
docking zone.
1.3 Perimeter Wire Setup for Docking Zone and Non-Docking Zone
The perimeter wire setup in a docking and non-docking zone is identical in terms of placement and
fastening. In a non-docking zone, the perimeter wire ends will attach to the perimeter switch, where in the
docking zone they attach to the docking station board.
Puncture the plastic covering of the perimeter wire with your finger and feel around inside the center of the
wire spool for the end of the wire. Pull the wire end out of the plastic covering. The plastic covering is
designed as a dispenser for the wire, so do not remove the wire spool from the covering.
IMPORTANT: It is necessary to first read this chapter (Docking Station & Perimeter Wire Setup) before
starting to layout the Perimeter Wire, in order to be aware of all setup rules and instructions.
Starting at the location of the Perimeter Switch or the Docking Station, begin pulling the perimeter wire out
of the plastic covering as you walk along the area of the lawn you are setting up. Be sure to leave enough
wire at the beginning, where the Perimeter Switch or the Docking Station will be located. In the Docking
Station zone leave 8 inches/20cm – see figure 1.8. For Perimeter Switch (none-docking zone) leave no
less than 5 feet (1.5 m) of wire at the beginning of the setup.
After removing enough wire within a given section, use the RoboRuler (see section 1.4) to identify the
correct placement of the wire. Initially place a minimum number of pegs to fasten the wire down. You will
want to test the proper position of the wire for the edge mowing process and you may find some areas
where you will need to move the wire position slightly. See section 2.8 for details on testing. You can lightly
insert pegs into the ground by hand to hold the wire temporarily in place before driving the pegs to the
ground level with a hammer.

16
1.4 Using The RoboRuler
The Robomow includes a ruler style measurement stick called a RoboRuler that is used to help position
the perimeter wire along walls, fences, sidewalk, driveways, flower beds and other perimeter zones. There
are two basic measurements that are used on the RoboRuler. The shorter distance is used along
perimeter edges where the area outside the immediate perimeter (about 12 inches/30 cm) is free of
obstacles and is the same relative height as the perimeter edge. The longer distance is used along
perimeter edges where the area outside the immediate perimeter has obstacles or differences in the height
along the perimeter edge. See Figure 1.9.
Note: Use the short distance of the RoboRuler to set the wire position around the obstacle while creating a
Perimeter Island (See section 1.8).
1.5 Fastening The Wire To The Ground
It is not necessary to bury the perimeter wire, though you may do so if you wish, up to 3 inches (7.5 cm).
Small pegs or stakes are supplied with the Robomow and they are used to fasten and hold the perimeter
wire to the ground, below grass level. They resemble a small tent stake. When properly fastened to the
ground, the wire and pegs will soon disappear under the growth of new grass. The pegs simply hold the
wire in place at the ground level to allow for the grass to grow over it. Pegs should be driven at distances
between one another that will keep the wire down below the grass level and prevent it from becoming a
tripping hazard while in the process of being covered with grass growth. See Figure 1.10. Remember, you
want to test the wire setup for edge mowing before you fill in the additional pegs. See section 2.8 and 2.9
for details on testing.
Damage to the eye is possible. Use proper
eye protection and wear appropriate work
gloves when hammering the pegs.
Hard or dry ground may cause pegs to
break when driving them in. In extreme
cases, watering the lawn where the pegs
will be driven can be beneficial.

1.6 Corners & Sharp Turns
Care must be taken not to create a corner sharper than 90 degrees when setting up the perimeter wire. A
corner sharper than 90 degrees can cause the Robomow to lose track of the perimeter wire. In situations
where a corner may require a wire placement of less than a 90-degree angle, placement can be adjusted
using several angles to avoid this. See Figure 1.11.
1.7 Narrow Areas And Narrow Passes
There is a limitation to the width of an area the Robomow can effectively navigate through in order to move
into another larger, but attached area. A narrow pass is defined as an area that narrows down
substantially from the initial width and in which the Robomow must pass through in order to access and cut
other zones, an hourglass shape. The minimum distance for an effective narrow pass is 5.5 feet (1.7 m)
between perimeter wires. The larger a pass can be made, the better access Robomow will have between
the zones. This will greatly improve the effectiveness and efficiency of the mower. See Figure 1.14. For
an area that is narrow in width, but does not provide access to another section of the same zone, there is a
minimum working distance of 5.5 feet (1.7m). Figure 1.14.

1.8 Defining Obstacles-Perimeter Islands
Many obstacles can be left in the lawn without consideration to excluding them using the perimeter wire.
The basic rule of thumb is that the obstacle must be at least 6 inches (15 cm) high from the ground and the
obstacle must be relatively rigid. Good examples of these kinds of obstacles include many trees, phone
poles and power poles. When obstacles like this are encountered in the lawn, it is easiest to allow the
Robomow to bump into them, causing the bumper sensor to activate and assist in navigating around them.
Young, sapling aged trees are not good examples, as they are not very rigid. Other obstacles that are not
rigid and at least 6 inches high (15 cm) must be protected from the Robomow using the perimeter wire.
This is done as part of the setup process and is commonly referred to as a perimeter island. Good
examples of these types of obstacles are flowerbeds, islands, small trees and low bed edging.
The Robomow is designed to easily work in the lawn with both types of obstacles, however, for the most
gentle and silent operation, it is preferable to demarcate all fixed objects in and around the working area. If
you are unsure about a particular obstacle, it is best to exclude it with the perimeter wire. It will have no
effect on the efficiency of the mower and can later be removed if not needed.
To create a perimeter island, take the wire from the perimeter section closest to the obstacle and peg the
wire around the obstacle, returning back to the same spot of the perimeter. There are two keys to setting
up the perimeter wire to exclude an obstacle; 1) place the wire going to the obstacle from the perimeter
and the wire going from the obstacle to the perimeter adjacent to one another. This area is between the
obstacle and the normal lawn edge where the perimeter wire is set up; and 2) follow the direction of
installation when going to the interior of the lawn to exclude an obstacle. While the picture in figure 1.12
may appear to have the wires leading to and from the island set up with a space between them, this is for
illustration purposes only. A proper placement of these two wires is to have them touching one another,
but in no event should they be farther than 1/8 of an inch (3 mm) apart from one another. For the best
results, place both wires under the same peg when placing them in the lawn around obstacles. Placement
of the wires as described allows for the signal in the two wires to cancel, but only in the area where they
are installed adjacent to one another and touching. By canceling the signal in this section, the Robomow is
free to cross this area but will still recognize the signal of the perimeter island. See Figure 1.30.

The Robomow can freely move across this section, but will still
recognize the perimeter island. By allowing this, multiple obstacles in a

its’ efficiency.

1.9 Multiple Zones/Areas
As mentioned earlier, your home may require more than one zone to be set up in order for the Robomow
to work in all of your lawn effectively. Having two or even three zones does not affect the efficiency of the
Robomow and in many circumstances is more desirable than one large zone. Where grass areas are not
contiguous, or are separated by fences or other objects, it is also recommended to make each of these a
separate zone. A simple but effective and common way to set the Robomow up is to have one zone for
the front yard and one for the back yard, where one zone is a docking zone.
The key is to set up the zones that will allow the Robomow to operate with the greatest efficiency, even if it
is more than one or two zones. You will quickly find that mowing the lawn in these zones is an easy
process that will allow you greater flexibility in your mowing habits. The Robomow gives you the ability to
control the operating time for each zone independently, up to four different zones. In this way, if one zone
needs a shorter operating time than another, it can easily be set for such a process. See Chapter 6,
Operator Settings and Advanced Features for detailed information on how to use this feature. There are
several ways to set up these zones, including the placement of the Perimeter Switch, depending on the
actual layout of the lawn. Examples are given in figures 1.14 and 1.15.
