2 Description of the System
2.1 System Components
The SKR001 is a laser tool for general construction and levelling applications
such as
•
Setting forms
•
Checking grades
•
Controlling depths for excavations
If set up within the self-levelling range, the SKR001 automatically levels
to create an accurate horizontal or vertical plane of laser light. Once the
SKR001 has levelled, the head will start rotating and the SKR001 is ready
for use. 30 seconds after the SKR001 has completed the levelling, the H.I.
Alert system becomes active and protects the SKR001 against changes in
elevation caused by movement of the tripod to ensure accurate work.

Check the details of the model you have purchased.
☞
Some of the battery cartridges may not be available depending
on your region of residence.
6.1 Operating Principles
•
The battery must be charged before using it the rst time, because it
is delivered with an energy content as low as possible or might be in
sleep mode.
•
Charge the battery cartridge at room temperature at +10 °C to +40 °C/
+50 °F to +104 °F. At cold temperature, charging may not start
•
It is normal for the battery to become warm during charging. Using
the chargers recommended by Makita, it is not possible to charge the
battery once the temperature is too high
•
For new batteries or batteries that have been stored for a long time
(> three months), it is effectual to make a discharge/charge cycle
•
For Li-Ion batteries, a single discharge/charge cycle is sufcient. We
recommend carrying out the process when the battery capacity indic-
ated on the charger or on a Makita product deviates signicantly from
the actual battery capacity available.
• The batteries can be operated from −20 °C to +55 °C/−4 °F to +131 °F
•
Low operating temperatures reduce the capacity that can be drawn;
high operating temperatures reduce the service life of the battery
6.2 Battery for SKR001
1. Remove the Makita battery from the SKR001.
2. Charge externally with original Makita charger.
CAUTION
Battery tray not locked securely
If the battery tray is not locked securely, it may fall out of the SKR001
accidentally and might cause damage and injury.
Precautions:
▶
Install and lock the battery tray securely.

7 Accuracy Adjustment
•
It is the responsibility of the user to follow operating instructions
and to periodically check the accuracy of the laser and work as it
progresses.
•
The SKR001 is adjusted to the dened accuracy specication at the
factory. It is recommended to check the laser for accuracy upon
receipt and periodically thereafter to ensure accuracy is maintained.
If the laser requires adjustment, contact your nearest authorised ser-
vice centre or adjust the laser using the procedures described in this
chapter.
•
Only enter the accuracy adjustment mode when you plan to change
the accuracy. Accuracy adjustments should only be performed by a
qualied individual that understands basic adjustment principles.
•
It is recommended to perform this procedure with two people on a
relatively at surface.
7.1 Checking the Level Accuracy
1. Place the SKR001 on a at, level surface or tripod approximately
30 m (100 ft) from a wall.

9 Care and Transport
9.1 Transport
When transporting the equipment in the eld, always make sure that you
•
either carry the product in its original container,
•
or carry the tripod with its legs splayed across your shoulder, keeping
the attached product upright.
Never carry the product loose in a road vehicle, as it can be affected by
shock and vibration. Always carry the product in its container and secure it.
When transporting the product by rail, air or sea, always use the complete
original Makita packaging, container and cardboard box, or its equivalent, to
protect against shock and vibration.
When transporting or shipping batteries, the person responsible for the
product must ensure that the applicable national and international rules and
regulations are observed. Before transportation or shipping, contact your
local passenger or freight transport company.
Exposing the product to high mechanical forces, for example through fre-
quent transport or rough handling, or storing the product for a long time
may cause deviations and a decrease in the measurement accuracy. Period-
ically carry out test measurements and perform the eld adjustments indic-
ated in the User Manual before using the product.
9.2 Storage
Respect the temperature limits when storing the equipment, particularly in
summer if the equipment is inside a vehicle. Refer to 10 Technical Data for

For Li-Ion batteries
•
A storage temperature range of 0 °C to +30 °C / +32 °F to +86 °F in
a dry environment is recommended to minimize self-discharging of the
battery
•
At the recommended storage temperature range, batteries containing
a 40% to 50% charge can be stored for up to one year. After this
storage period the batteries must be recharged
9.3 Cleaning and Drying
•
Blow dust off lenses and prisms.
•
Never touch the glass with your ngers.
•
Use only a clean, soft, lint-free cloth for cleaning. If necessary, moisten
the cloth with water or pure alcohol. Do not use other liquids; these
may attack the polymer components.
Dry the product, the transport container, the foam inserts and the accessor-
ies at a temperature not greater than 40 °C/104 °F and clean them. Remove
the battery cover and dry the battery compartment. Do not repack until
everything is completely dry. Always close the transport container when
using in the eld.
